A total lunar eclipse will be visible across most of North America on the night of March 13-14, 2025, offering a rare celestial event for skywatchers. The eclipse, which will last 1 hour and 6 minutes, will be best observed from the western regions of the United States and Canada but will be visible from coast to coast.

This marks the first total lunar eclipse widely seen in North America in over two years. The phenomenon occurs when the Earth moves directly between the sun and the moon, casting a shadow that gives the moon a reddish hue, often referred to as a "Blood Moon."

Viewing Conditions and Timing

Observers on the West Coast will have the best conditions, as the eclipse will occur during mid-to-late evening hours. Across the Atlantic, the event will be visible at dawn on March 14, while in parts of Europe and Africa, the moon will set while still in total eclipse. In New Zealand and parts of Siberia, the eclipse will be visible as the moon rises.

The event will progress through several phases, beginning with the moon entering Earth's outer shadow, or penumbra, before moving into the umbra, where the total eclipse occurs. The moon will then gradually emerge from the shadow, returning to its usual brightness.

Scientific Significance

Lunar eclipses provide a unique opportunity for scientific observation, including studies of Earth’s atmosphere and its impact on light refraction. The color of the moon during totality can vary depending on atmospheric conditions, including the presence of dust or volcanic particles.

Astronomers and amateur skywatchers are encouraged to take advantage of this event. Observatories and astronomy groups may organize public viewing sessions, and individuals are advised to find locations with minimal light pollution for the best experience.

Public Engagement

Space enthusiasts are encouraged to document the eclipse, with Space.com inviting readers to submit photographs and observations. Those interested can send their images and comments to spacephotos@space.com.

With clear weather, the March 2025 lunar eclipse is expected to be a spectacular event, providing a rare opportunity to witness one of nature’s most striking astronomical displays.





Rare Seven-Planet Alignment to Light Up the Night Sky

Saturday, March 1, 2025 / No Comments

This phenomenon occurs when multiple planets appear to form a straight line in the night sky. According to Dr. Greg Brown, an astronomer at the Royal Observatory Greenwich, “A planetary parade happens when several planets become visible at the same time. The spectacle’s impact depends on the number of planets involved and how easily they can be seen.”

While all seven planets—Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune—will technically align, some will be more visible than others. Brown explains that Mercury, Neptune, and Saturn will be positioned near the horizon, making them challenging to spot, particularly in the fading twilight. Uranus and Neptune, both faint and distant, will require a telescope or binoculars. However, Venus, Jupiter, and Mars will be bright and easily visible to the naked eye.

How and When to Watch

Planetary alignments occur because all the planets orbit the Sun within the same general plane, known as the ecliptic. As they move at different speeds and distances, there are moments when they appear to align from Earth’s perspective.

Dr. Shyam Balaji, a researcher in astroparticle physics and cosmology at King’s College London, advises that the best viewing time for the UK is shortly after sunset on 28 February, when the planets will be visible above the western horizon. Similar viewing conditions apply in the US (about 30 minutes after sunset) and Australia (looking north after sunset). For the best experience, stargazers should avoid bright city lights and consider using stargazing apps to locate the planets.

While planetary groupings of three to five planets are relatively common, full seven-planet alignments are rare, with the next one not expected until 2040. A similar event occurred last June, but only two planets were visible without special equipment. This month, Venus, Mars, and Jupiter will be the easiest to spot, while Saturn and Mercury will be near the horizon, making them more difficult to observe. Uranus and Neptune, though included in the alignment, will require binoculars or a telescope.

For those using telescopes, Brown suggests looking for the moons of Jupiter or the crescent shape of Venus to enhance the experience. As spring progresses, the planets will slowly drift apart, making this a fleeting but awe-inspiring moment in the night sky.

Mark Your Calendar

This planetary parade is a rare opportunity for both amateur and seasoned astronomers to witness the planets in alignment. Whether gazing with the naked eye or through a telescope, this celestial event offers a breathtaking reminder of the vastness of our solar system.

MIT Prepares to Launch Groundbreaking Payloads to the Moon's South Pole

Tuesday, February 25, 2025 / No Comments

 

miniature helper bots

MIT is gearing up to make history once again by sending three innovative payloads to the Moon, aiming to support future astronaut missions and contribute to the establishment of a permanent lunar base.

In the coming days, if weather conditions cooperate, MIT’s engineering and science teams will launch their payloads toward the Moon’s south pole. This region, with its eternally shadowed areas, is believed to potentially harbor frozen water deposits—an essential resource for sustaining human life on the Moon and powering deeper space missions.

As part of NASA’s Artemis III mission, scheduled for 2027, astronauts will set foot on the Moon’s south pole for the first time. Ahead of this historic event, MIT’s payloads will gather critical data to help prepare the Artemis crew for navigating the Moon’s icy terrain.

A Closer Look at the Payloads

The MIT payloads feature two groundbreaking technologies:

  • A Depth-Mapping Camera: Utilizing time-of-flight technology, this camera will capture the first-ever 3D images of the lunar surface, offering invaluable insights for training astronauts and enhancing spacesuit technologies.
  • The “AstroAnt” Mini-Rover: This thumb-sized robot will maneuver on the main rover’s roof, monitoring temperature and potentially evolving into a fleet of helper bots for future missions.

The third payload, the “HUMANS” project, is a silicon wafer etched with messages from people around the world, inspired by NASA’s iconic Golden Record.

All three technologies will hitch a ride on a larger rover developed by Lunar Outpost, with the entire mission launching aboard a SpaceX Falcon 9 rocket. The lunar landing is planned for March 6, marking the first time MIT technology will touch the Moon’s surface since the Apollo program.

Mission Objectives and Legacy

The mission, known as IM-2, will explore the Mons Mouton Plateau near Shackleton Crater. Beyond MIT’s payloads, the mission will employ various tools, including an ice drill and a robotic “hopper,” to seek water-ice deposits in hard-to-access regions.

MIT’s participation is led by the Space Exploration Initiative (SEI) within the Media Lab. The project represents a deep connection to the Institute’s history, with contributions from students, alumni, and faculty across multiple departments.

Dava Newman, Apollo Program Professor of Astronautics and Director of the MIT Media Lab, emphasizes the broader vision:
“Our goal is not just to visit the Moon but to build a thriving ecosystem that supports humanity’s expansion into space.”

Looking Forward

As MIT prepares to send its technologies to the Moon, the community is invited to watch the live broadcast of the landing on campus. Researchers are optimistic that this mission is the first step toward a sustained human presence on the Moon and beyond.

Ariel Ekblaw, principal investigator for MIT’s role in the IM-2 mission, adds:
“This mission is about inspiring the next generation of explorers. It brings together the entire MIT community on a foundational mission that could lay the groundwork for a permanent lunar settlement.”

Elon Musk Clashes with Danish Astronaut Over Alleged ISS Abandonment Claim

Elon Musk has found himself at the center of a controversy after a Danish astronaut challenged his claim that former US President Joe Biden intentionally left two American astronauts, Butch Wilmore and Suni Williams, stranded on the International Space Station (ISS) for political reasons.

During a Fox News interview alongside Donald Trump, Musk asserted that NASA’s Wilmore and Williams were abandoned on the orbital outpost. Andreas "Andy" Mogensen, a European Space Agency astronaut with two ISS missions under his belt, refuted Musk's statement, calling it a "lie" on X (formerly Twitter).

In response, Musk used an offensive slur against Mogensen and claimed that his company, SpaceX, had previously offered to bring the astronauts back, though he did not provide specifics.

The astronauts had initially traveled to the ISS in June on a Boeing Starliner for an eight-day test mission. However, thruster issues led NASA to opt for an uncrewed return of the Starliner and to assign their return to SpaceX’s Crew-9 mission.

Although initially scheduled for February, their return was postponed to March due to SpaceX delays. Mogensen pointed out that the return plan had been in place since last September, questioning Musk's narrative.

Musk, CEO of SpaceX and Tesla, also leads the Department of Government Efficiency under the Trump administration. His history of controversial remarks includes a 2018 defamation case in which he was acquitted after calling British cave explorer Vernon Unsworth a “pedo guy” during the Thailand cave rescue.




NASA’s Webb Telescope Unveils Mystery Behind Phoenix Galaxy Cluster’s Extreme Star Formation

A groundbreaking study using NASA’s James Webb Space Telescope (JWST) has provided new insights into the Phoenix galaxy cluster, revealing the key process behind its unexpected starburst activity.

Scientists from MIT and other institutions have discovered that the cluster’s central galaxy is undergoing extreme cooling, fueling an unusually high rate of star formation—far beyond what astronomers would expect for a system of its age.

The Phoenix cluster, located 5.8 billion light-years away, is the largest known galaxy cluster of its kind. Typically, such massive clusters are "red and dead," meaning they no longer form stars. However, researchers previously observed that the central galaxy was producing stars at an astonishing rate of 1,000 per year—far exceeding the norm.

Using JWST’s infrared capabilities, researchers mapped the presence of “warm” gas in the cluster’s core, bridging the gap between its previously observed hot and ultracold gas phases. This discovery confirms that the gas is cooling within the cluster itself, rather than being funneled in from other galaxies.

“For the first time, we have a complete picture of the hot-to-warm-to-cold process of star formation, something never before observed in any galaxy,” said Michael Reefe, lead author and physics graduate student at MIT’s Kavli Institute for Astrophysics and Space Research.

The findings suggest that Phoenix may represent a unique phase that all galaxy clusters undergo at some point, or it could be an outlier with conditions unlike any other known system. Scientists are now working to determine why this particular cluster is experiencing such an intense starburst.

“This new work has given us a fresh way to observe and understand these systems,” said MIT astrophysicist Michael McDonald, a co-author of the study. “We now understand what is driving this star formation—but the question remains: why is Phoenix different?”

The study, published in Nature, opens new doors for exploring the cooling mechanisms of galaxy clusters and their impact on cosmic evolution.

Hubble Space Telescope Captures Stunning 'Bullseye' Galaxy, Offering Glimpse into Cosmic Collisions

Wednesday, February 5, 2025 / No Comments

LEDA 1313424, aptly nicknamed the Bullseye, is two and a half times the size of our Milky Way and has nine rings — six more than any other known galaxy. | Credit: NASA, ESA, Imad Pasha (Yale), Pieter van Dokkum (Yale)The Hubble Space Telescope has captured an extraordinary image of a galaxy that resembles a giant bullseye, a discovery that provides valuable insights into galactic collisions. The galaxy, formally known as LEDA 1313424, is approximately two and a half times the size of our Milky Way and is surrounded by a series of concentric rings. These rings were created when a smaller blue dwarf galaxy passed directly through the center of LEDA 1313424 around 50 million years ago, sparking the formation of new stars and leaving behind a series of "ripples" in the galaxy's structure.

Astronomers have long theorized that such collisions could produce rings, but this is the first time that so many rings—eight—have been observed in a single galaxy. In fact, one of the W.M. Keck Observatory’s findings suggests a ninth ring. The discovery marks the most rings ever seen in any galaxy and provides strong evidence to support computational models that predict how such galactic interactions unfold. Researchers are excited to learn that this event, a rare moment in cosmic history, could be confirmed with this stunning image, which also showcases the lasting impact of galaxy collisions.

The lead researcher, Imad Pasha from Yale University, describes the find as serendipitous, as he stumbled upon the galaxy while analyzing a ground-based imaging survey. While galactic collisions are common, it is unusual for a smaller galaxy to pass directly through the center of a larger one, creating such a symmetrical and captivating pattern. This collision has not only left behind multiple rings but has also triggered new regions of star formation, thanks to the mixing of gas and dust ejected during the event.

Scientists now believe that there might be even more galactic rings hidden in the distant reaches of the galaxy. As the Hubble Space Telescope continues to provide unprecedented views of the universe, researchers are hopeful that future observations will reveal more such collisions and help further understand the dynamics of galaxy formation.

The discovery also supports long-standing theoretical models about how galactic rings expand outward from the point of impact. This observation will not only enhance our knowledge of cosmic events but may lead to even more discoveries with upcoming space telescopes, such as NASA's Nancy Grace Roman Space Telescope, which will be launched in the near future.

This stunning visual and the cosmic revelations it provides remind us of the beauty and complexity of the universe, where collisions and interactions between galaxies can result in incredible and rare phenomena like the "Bullseye" galaxy.

 

Newly Discovered Asteroid 2024 YR4 Has Slim Chance of Earth Impact in 2032

Friday, January 31, 2025 / No Comments
an asteroid illustrationScientists are closely monitoring a newly discovered asteroid that has a slight chance of colliding with Earth in 2032. Named 2024 YR4, the asteroid was first detected on December 27 by an observatory in Chile and has since been tracked by multiple telescopes worldwide.

According to data from NASA and the European Space Agency (ESA), the asteroid has a 1.2% chance of impact on December 22, 2032. However, experts stress that this means there is a 98.8% probability it will pass safely by Earth.

Measuring between 131 and 328 feet (40 to 100 meters) in width, 2024 YR4 is comparable in size to a large building. If it were to strike Earth, it could cause regional devastation, with potential blast damage reaching up to 31 miles (50 kilometers) from the impact site, said Dr. Paul Chodas, director of NASA’s Center for Near Earth Object Studies (CNEOS).

Tracking the Threat

The asteroid was initially spotted by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Chile, part of NASA’s asteroid detection program. Since then, astronomers have used telescopes in New Mexico, Chile, and Denmark to refine its trajectory.

Currently, 2024 YR4 is about 28 million miles (45 million kilometers) away and moving farther from Earth. Scientists will continue tracking the asteroid until April, when it becomes too faint to observe. If uncertainty remains about its path, the asteroid will stay on NASA and ESA’s asteroid risk lists until it returns to view in 2028.

"The longer we observe an asteroid, the more accurately we can predict its future path," said NASA navigation engineer Davide Farnocchia. Experts expect that additional data will likely eliminate the risk of impact entirely.

Prepared for the Worst

While it is unlikely that 2024 YR4 will strike Earth, international space agencies are prepared to act if necessary. The United Nations-endorsed International Asteroid Warning Network (IAWN) and the Space Mission Planning Advisory Group (SMPAG) have been activated to assess the situation.

Potential response strategies include asteroid deflection missions or evacuation plans if the asteroid remains a threat. NASA’s Double Asteroid Redirection Test (DART), conducted in 2022, successfully demonstrated that crashing a spacecraft into an asteroid could alter its course.

For now, scientists emphasize that 2024 YR4 does not pose an immediate danger. “Our priority is to continue monitoring its position to rule out any risk,” said Farnocchia.

If the asteroid remains on its current path, further tracking in 2028 will provide the final confirmation of its safety.

Caltech Researchers Take First Steps Toward Lightsail-Powered Interstellar Travel

Thursday, January 30, 2025 / No Comments

In a groundbreaking step toward interstellar exploration, researchers at Caltech have developed a method to test ultrathin "lightsails"—a revolutionary concept that could one day enable spacecraft to travel to distant star systems like Alpha Centauri.

Inspired by the Breakthrough Starshot Initiative, a program launched in 2016 by Stephen Hawking and Yuri Milner, the lightsails aim to achieve unprecedented speeds by harnessing the power of laser propulsion. Unlike traditional spacecraft, these tiny probes equipped with reflective membranes could be propelled to interstellar distances using high-powered lasers from Earth.

"These lightsails have the potential to travel faster than anything we've ever built, opening the door to direct exploration of star systems currently accessible only through telescopes," said Harry Atwater, Chair of Caltech’s Division of Engineering and Applied Science.

Atwater and his team have now taken the first experimental steps toward this ambitious goal. Using cutting-edge nanotechnology, they created a miniature tethered lightsail just 50 nanometers thick and developed an advanced platform to measure how laser radiation pressure interacts with it.

Turning Theory into Reality

One major challenge in lightsail development is understanding how the sails behave under the intense force of laser beams. To address this, the Caltech researchers crafted a silicon nitride "trampoline" membrane, only 40 microns across, suspended at its corners by delicate springs. By directing a visible laser at the sail, the team measured its motion and stiffness with remarkable precision—down to the picometer scale.

"The dynamics of a tethered sail are complex, but this setup allowed us to measure both the force and power of the laser with extraordinary accuracy," explained Lior Michaeli, a postdoctoral scholar and co-lead author of the study.

To overcome challenges like heating effects from the laser, the researchers developed a custom-built interferometer to isolate and measure even the smallest vibrations caused by radiation pressure. This breakthrough allowed them to mimic real-world conditions, such as a sail being hit by a laser at an angle, and gather critical data on how the sail responds.

What’s Next?

The team’s work is only the beginning. Future research will explore how advanced materials, like nanostructured surfaces, can stabilize a lightsail and keep it aligned with the laser beam. "If a lightsail drifts or rotates out of position, we need it to correct itself automatically," said co-author Ramon Gao, a graduate student at Caltech.

The ultimate vision is to create a freely accelerating lightsail 10 square meters in size and less than 100 nanometers thick. While this first experiment involved a tethered prototype, it marks a crucial milestone in turning science fiction into reality.

The research, published in Nature Photonics on January 30, was supported by the Air Force Office of Scientific Research and the Breakthrough Starshot Initiative.

As humanity continues its quest to explore the stars, Caltech’s work on lightsails is pushing the boundaries of what’s possible, bringing us closer to unlocking the secrets of interstellar travel.
