One of the beauties of modern-day space telescopes is that the data they produce, which is eventually wholly released to the public, contains useful information about much more than their primary mission objective. Other astronomers can then sift through the data using their own ideas, and in many cases, their own algorithms. Recently, a team from Poland turned a flare-searching algorithm on TESS’s planet-hunting data, and found an astonishing 25,229 stars with solar flares in the data set.

Within the next decade, several space agencies and commercial space partners will send crewed missions to the Moon. Unlike the “footprints and flags” missions of the Apollo Era, these missions are aimed at creating a “sustained program of lunar exploration.” In other words, we’re going back to the Moon with the intent to stay, which means that infrastructure needs to be created. This includes spacecraft, landers, habitats, landing and launch pads, transportation, food, water, and power systems. As always, space agencies are looking for ways to leverage local resources to meet these needs.

Rocket Lab is launching the first-ever private mission to Venus. Europe is considering space-based solar power. A new method to detect exoplanets. More evidence about the Moon’s origins. Webb’s largest every image. All that and more in this week’s episode of Space Bites.

In 2019 the Event Horizon Telescope gave us our first direct image of a black hole. It was a powerful image, but not one with much detail. It looks like a blurry orange donut. To be fair, the real meat of the discovery was in the data, not the image. And as a recent study shows, there’s a great deal more in the data than what we’ve seen.

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?

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.

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.

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.

A team of scientists using the James Webb Space Telescope have just released the largest image taken by the telescope so far. The image is a mosaic of 690 individual frames taken with the telescope’s Near Infrared Camera (NIRCam) and it covers an area of sky about eight times as large as JWST’s First Deep Field Image released on July 12. And it is absolutely FULL of early galaxies, many never seen before. Additionally, the team may have photographed one of the most distant galaxies yet observed.

Meet R136a1, the most mass star known. Located in the Large Magellanic Cloud, it’s a hulking behemoth weighing somewhere between 150 and 200 times the mass of the Sun. Understanding the upper limit of stars helps astronomers peace together everything from the life cycles of stars to the histories of galaxies.

This Fall, the fifth crewed mission (Crew-5) of the NASA Commercial Crew Program will depart for the International Space Station (ISS). This mission will see four astronauts launch from the Kennedy Space Center in Flordia aboard a SpaceX Crew Dragon (atop a Falcon 9 rocket). Once they reach the ISS, they will join the crew of Expedition 67 and conduct science experiments as part of Expedition 68. The mission commander of this flight, Nicole Aunapu Mann, is a naval aviator and test pilot with a distinguished military career. She will also be the first Indigenous woman ever to go to space!

We have discovered thousands of exoplanets in recent years. Most have them have been discovered by the transit method, where an optical telescope measures the brightness of a star over time. If the star dips very slightly in brightness, it could indicate that a planet has passed in front of it, blocking some of the light. The transit method is a powerful tool, but it has limitations. Not the least of which is that the planet must pass between us and its star for us to detect it. The transit method also relies on optical telescopes. But a new method could allow astronomers to detect exoplanets using radio telescopes.

The Orion Nebula is a giant cloud of gas and dust that spans more than 20,000 times the size of our own solar system. It one of the closest active star-forming regions to Earth, and is therefore one of the most observed and photographed objects in the night sky. The venerable Hubble Space Telescope has focused on the Orion Nebula many times, peering into giant cavities in the hazy gas, and at one point, Hubble took 520 images to create a giant mosaic of this spellbinding nebula.

There’s an ocean of human-made garbage floating through Earth’s seas. From plastic straws to beverage bottles and food wrappers, the ocean waters are this planet’s fastest-growing junkyard. Some of the plastic gets ground into little beads, and ends up in the food chain, with humans at the top. For that reason, and many others, the European Space Agency is tracking ocean-bound plastics through the auspices of the MARLISAT project. It’s one of 25 efforts created to identify and trace marine litter as it moves through the world’s waterways. The ultimate goal is to help countries reduce ocean litter, particularly plastics.

Piecing together the history of the Solar System from the traces left behind isn’t easy. Bit by bit, however, we’re working it out. This month, new research examining the composition of lunar meteorites offers compelling evidence that the Moon and the Earth were formed from the same material, perhaps in the aftermath of a cataclysmic collision some 4.5 billion years ago.
