NASA and Axiom Space Inc. provided a first, limited look at the new spacesuits that will be worn by the next astronauts to land on the Moon. The Axiom Extravehicular Mobility Unit (AxEMU) spacesuit that will be worn for the Artemis missions was only partially revealed at an event at Johnson Space Center in Houston, in order not to give away any proprietary information about the suit.

Remember how exciting it was in 2017 when a total solar eclipse crossed the United States? We’re in for two more well-placed eclipses over the next year, so it’s time to get organized to take advantage of these unparalleled celestial events.

Nearly eight years after its historic Pluto flyby, NASA’s New Horizons probe is getting ready for another round of observations made from the icy edge of the solar system — and this time, its field of view will range from Uranus and Neptune to the cosmic background far beyond our galaxy.

According to the most widely-accepted model of cosmology, the Universe began roughly 13.8 billion years ago with the Big Bang. As the Universe cooled, the fundamental laws of physics (the electroweak force, the strong nuclear force, and gravity) and the first hydrogen atoms formed. By 370,000 years after the Big Bang, the Universe was permeated by neutral hydrogen and very few photons (the Cosmic Dark Ages). During the “Epoch of Reionization” that followed, the first stars and galaxies formed, reoinizing the neutral hydrogen and causing the Universe to become transparent.

There’s something menacing about red dwarfs. Human eyes are accustomed to our benevolent yellow Sun and the warm light it shines on our glorious, life-covered planet. But red dwarfs can seem moody, ill-tempered, and even foreboding.

Planetary exploration, specifically within our own Solar System, has provided a lifetime of scientific knowledge about the many worlds beyond Earth. However, this exploration, thus far, has primarily been limited to orbiters and landers/rovers designed for surface exploration of the celestial bodies they visit. But what if we could explore subsurface environments just as easily as we’ve been able to explore the surface, and could some of these subsurface dwellings not only shelter future astronauts, but host life, as well?

Hubble Space Telescope’s Deep Field revealed thousands of galaxies in a seemingly empty spot in the sky. Now, the James Webb Space Telescope has taken deep field observations to the next level with its COSMOS-Web survey, revealing 25,000 galaxies in just six pictures, the first from this new survey.  

There are plenty of places for life to hide. Even on our blue planet, where we know there is abundant life, it is sometimes difficult to predict all the different environments it might crop up in. Exploring worlds other than our own for life would make it exponentially more difficult to detect it because, realistically, we don’t really know what we’re looking for. But life will probably present itself with some sort of pattern. And there is one new technology that is exceptional at detecting patterns: machine learning. Researchers at the SETI Institute have started working on a machine-learning-based AI system that will do just that.

A newly discovered asteroid called 2023 DW has generated quite a buzz over the past week, due to an estimated 1-in-670 chance of impact on Valentine’s Day 2046. But despite a NASA advisory and the resulting scary headlines, there’s no need to put an asteroid doomsday on your day planner for that date.

Over 13 billion years ago, the first galaxies in the Universe formed. They were elliptical, with intermediate black holes (IMBHs) at their centers surrounded by a halo of stars, gas, and dust. Over time, these galaxies evolved by flattening out into disks with a large bulge in the middle. They were then drawn together by mutual gravitational attraction to form galaxy clusters, massive collections that comprise the large-scale cosmic structure. This force of attraction also led to mergers, where galaxies and their central black holes came together to create larger spiral galaxies with central supermassive black holes (SMBHs).

The picture of the Moon in the banner might not look all that spectacular, but it is absolutely astounding from a technical perspective. What makes it so unique is that it was taken via a telescope using a completely flat lens. This type of lens, called a metalens, has been around for a while, but a team of researchers from Pennsylvania State University (PSU) recently made the largest one ever. At eight cm in diameter, it was large enough to use in an actual telescope – and produce the above picture of the Moon, however, blurred it might be.

“It is possible even with existing technology, if done in the most efficient ways. New methods are needed, but none goes beyond the range of present-day knowledge. The challenge is to bring the goal of space colonization into economic feasibility now, and the key is to treat the region beyond Earth not as a void but as a culture medium, rich in matter and energy. Then, in a time short enough to be useful, the exponential growth of colonies can reach the point at which the colonies can be of great benefit to the entire human race.”

A world-famous 17th-century astronomer credited with discovering Saturn’s moon Titan may have needed glasses, according to a recent paper in the Royal Society Journal of the History of Science.

The official verdict on Artemis 1. Canadian kids discovered something NASA didn’t know. Was there a Dark Big Bang? The next bright comet for 2024.

The origins of Earth’s water is a complicated mystery that scientists have been untangling for decades. Life is impossible without water, so the origin of Earth’s life-giving water is a foundational question. As the power of our telescopes grows, researchers have made meaningful headway on the question.

Seen from space, regions of Mars around the south pole have a bizarre, pitted “Swiss cheese” appearance. These formations come from alternating massive deposits of CO2 ice and water ice, similar to different layers of a cake. For decades, planetary scientists wondered how this formation was possible, as it was long believed that this layering would not be stable for long periods of time.

One of the last times we did an article about a technology that could remove lunar dust from clothing, we opened it with a famous meme line from Star Wars. That also means we should probably avoid subjecting everyone to it again here. Still, the fact that we’ve had an opportunity to use it more than twice recently proves that removing lunar dust is a problem that has attracted a lot of attention in recent years. Artemis, NASA’s program to go back to the Moon this decade, is the cause of a lot of that attention as there are plenty of problems still to overcome. Some of those might be solved by a technique developed by a team at Washington State University (WSU) that uses every child’s gas that allows them to pound nails in with bananas – liquid nitrogen.

Artemis astronauts are returning to the Moon, and they’ll be following in Apollo’s footsteps when they go. But things are different this time. Not only is technology far more advanced, but so is the way we think about technology and how we design it.

For years, China has been dropping hints about its Long March 9 (CZ-9) rocket, a three-stage super-heavy variant of the Long March family. This launch vehicle will reportedly be capable of transporting up to 150,000 kg (165 tons) to Low Earth Orbit (LEO) and 54,000 kg (59.5 tons) to a trans-lunar injection. On March 2nd, the China Academy of Launch Vehicle Technology (CALT) announced (via the Chinese social media platform Weixin) that it had finished building the first propellant tank for the CZ-9.

When faced with a potentially mission-ending problem with NASA’s 15-year-old Interstellar Boundary Explorer (IBEX) spacecraft, engineers performed a time-honored procedure to fix it: they turned it off and then turned it back on again.

Every once in a while, the stars (or, in this case, satellites) align, and keen observers can receive an unexpected light show. That happened a few weeks ago at the Subaru telescope in Hawai’i. An eerie green laser seemingly appeared out of nowhere, as captured in a YouTube video uploaded to the telescope channel. Luckily, their source was no more ominous than a passing satellite, and with its video posted publicly, now everyone could enjoy the light show.
