Space and astronomy news
The James Webb Space Telescope continues to deliver surprise after surprise. Next up, a team of astronomers have identified likely candidates for proto-globular clusters. Clusters like these can help astronomers understand the evolution and ultimate fate of galaxies like our own.

What does the ancient coin found recently off the shores of Israel depict?
You never know what discoveries are waiting to be found in old records or artwork. A recent archaeological find sent us down just such an astronomical rabbit-hole, leading us to ideas that are fun and interesting to consider.

How do you fix the solar array of a spacecraft millions of miles away from the Earth hurdling through the void at thousands of miles per hour? Very carefully, that’s how.

Serhiy Prytula Charity Foundation signed a contract with ICEYE to provide the Government of Ukraine with the SAR reconnaissance data and full capabilities of one of ICEYE’s satellite already in orbit. The deal was closed with the money from the Foundation’s crowdfunding initiative.

In a recent study published in Earth and Planetary Astrophysics, a team of researchers from the University of Texas at Arlington, Valdosta State University, Georgia Institute of Technology, and the National Radio Astronomy Observatory estimated how many moons could theoretically orbit the Earth while maintaining present conditions such as orbital stability. This study opens the potential for better understanding planetary formation processes which could also be applied to identifying exomoons possibly orbiting Earth-like exoplanets, as well.

Scientists, futurists, and fans of science fiction alike have all dreamed that someday, humans would set foot on Mars. With the dozens of robotic orbiters, landers, rovers, and aerial vehicles we have sent there since the turn of the century (and the crewed missions that will follow in the next decade), the prospect that humans might settle on the Red Planet is once again a popular idea. Granted, the challenges of getting people there are monumental, to say nothing of the challenges (and hazards) associated with living there.
No matter how many people are willing to make a one-way trip and commit to living on Mars, establishing an outpost of humanity there will require some serious innovation and creative thinking! According to a new study by an international research team led by the Center of Applied Space Technology and Microgravity (ZARM), cyanobacteria might be able to withstand the difficult conditions and even thrive in Martian soil. This research suggests that astronauts could create biomass on Mars that would create a biological cycle.

The James Webb Space Telescope continues to deliver stunning images of the Universe, demonstrating that the years of development and delays were well worth the wait! The latest comes from Judy Schmidt (aka. Geckzilla, SpaceGeck), an astrophotographer who processed an image taken by Webb of the barred spiral galaxy NGC 1365. Also known as the Great Barred Spiral Galaxy, NGC 1365 is a double-barred spiral galaxy consisting of a long bar and a smaller barred structure located about 56 million light-years away in the southern constellation Fornax.

Early Earth was a wild and wooly place. In its first billion years, during a period called the Archean, our planet was still hot from its formation. Essentially, the surface was lava for millions of years. Asteroids bombarded the planet, and the place was still recovering from the impact that formed the Moon. Oceans were beginning to form as the surface solidified and water outgassed from the rock. The earliest atmosphere was actually rock vapor, followed quickly by the growth of a largely hot carbon dioxide and water vapor blanket. Earth was just starting land masses that later became continents. For decades, geologists have asked: what started continental formation?

Russian and US flight controllers decided to cut short a spacewalk by two cosmonauts outside the International Space Station yesterday after voltage fluctuations in Oleg Artemyev’s Orlan spacesuit caused concern. About halfway into a scheduled seven-hour EVA, Artemeyev was repeatedly ordered to drop what he was working on and return to ISS’s airlock.
“Drop everything and start going back right away,” was one of the translated messages heard during a NASA livestream of the spacewalk. “Oleg, you must return to the airlock as soon as possible because if you lose power, it is not only the pumps and the fan, you will lose comm. You have to go back.”

The Space Launch System (SLS) rocket and Orion spacecraft now sits on the launchpad, ready for liftoff on a journey around the Moon. This is the first time since 1972 that NASA has a human-rated spacecraft is ready to go beyond Earth orbit.
