Olympus Mons, located at the northwest edge of the Tharsis Montes region on Mars, was appropriately named. Based on readings obtained by the Mars Orbiter Laser Altimeter (MOLA), an instrument aboard NASA’s Mars Global Surveyor (MGS), this mountain is the tallest in the Solar System, standing 21.9 km (13.6 mi) tall – about two and a half times the height of Mount Everest (8.85 km; 5.5 mi). According to current estimates, this extinct shield volcano formed during Mars’ Hesperian Period (ca. 3.7 to 3 billion years ago), which was characterized by widespread volcanic activity and catastrophic flooding.

There are so many asteroids. Just in our own backyard, we’ve found over 30,000 Near Earth asteroids. Exploring them using traditional methods and launching a custom-made mission, like Hayabusa or OSIRIS-REx, would almost certainly be cost-prohibitive. So how can we assess whether they would make good targets for early asteroid mining missions? Ground imaging can help, but there’s nothing like being on-site on one of these asteroids to get a sense of what they are made of. Those visits would be much easier if we mass-produced the Asteroid Mobile Imager and Geologic Observer (AMIGO). 

Gamma Ray Bursts (GRBs) are the most powerful astrophysical phenomena in the universe. For a span of seconds to a few minutes, they can be the most powerful high-energy event in the sky, shining across billions of light years. But recently astronomers detected a GRB that lasted more than a thousand seconds, with two blasts of gamma rays that triggered the Fermi Gamma Ray Burst Monitor. It’s such a strange cosmic event that astronomers aren’t sure what caused it, but they do have a possible idea.

Three former insiders who have played a role in dealing with UFOs — or as they’ve now come to be known, unidentified anomalous phenomena — say the U.S. military knows more than what it’s been telling lawmakers about encounters with potentially alien technology.

It’s already been one year of operations for James Webb. We accumulated all the major scientific results, all the amazing images and spectra, all the important discoveries and controversies. Enjoy the ultimate recap of JWST’s first year.

Twinkle, twinkle little star, I wonder just how old you are.

The time to catch Comet T4 Lemmon is now, before it vanishes for another 36,000 years.

A pair of new studies set to be published in The Astronomical Journal examine new discoveries in the field of rogue planets, which are free-floating exoplanets that drift through space unbound by the gravitational tug of a star. They can form within their own solar system and get ejected, or they can form independently, as well. The first study examines only the second discovery of an Earth-mass rogue planet—the first being discovered in September 2020—while the second study examines the potential number of rogue planets that could exist in our Milky Way Galaxy.

We’re all used to seeing maps of the Milky Way rich with stars and nebulae. But, there are regions we can’t see or map using conventional methods. There’s no way to get outside the Galaxy to take pictures of the whole shebang.

One big question about Earth’s formation is, where did all the water come from? New data from the James Webb Space Telescope (JWST) shows newly forming planets in a system 370 light-years away are surrounded by water vapor in their orbits. Although astronomers have detected water vapor in protoplanetary disks before, this is the first time it’s been seen where the planets are forming.

Since the Viking 1 and 2 missions visited Mars in 1976, scientists have been confronted with mounting evidence that Mars once had flowing water on its surface. The images collected by the twin Viking landers and orbiters showed clear signs of ancient flow channels, alluvial deposits, and weathered rocks. Thanks to the dozens of additional orbiters, landers, and rovers sent that have been sent there since scientists have been getting a clearer picture of what Mars once looked like. At the end of this journey, they hope to find evidence (if there’s any to be found) that Mars once supported life and still does today.

Asteroids come in many shapes and sizes. Most are spherical, though many have a feature that can make them difficult to land on – they are essentially just collections of rocks loosely bound together by gravity. In space exploration jargon, they are known as “rubble piles.” Many of the asteroids humanity has visited are considered rubble piles, including Itokawa and Dimorphos, the destinations for Hayabusa and DART, respectively. But, as the trials of the Philae spacecraft showed when it tried to meet up with the comet 67P/Churyumov-Gerasimenko, landing on these objects with very low surface gravity can be difficult. Enter a new concept from researchers at the University of Colorado, Boulder. Their idea, known as Area-of-Effect Softbots (AoES), could help future asteroid explorers, and even miners, overcome some of the challenges facing them at these small bodies.

With its thick, cloudy atmosphere, Venus has long held mysteries about its surface. It was only in the late 20th century that astronomers had detailed observations of the Venusian landscape, with the Russian Venera landers in the 1970s and 1980s, and later the 1990 Magellan mission, which made high-resolution radar maps of the surface. There are many things we still don’t know, but one thing we do know is that the surface of Venus is young. And a new study in Nature Astronomy may know why.

There’s an old joke among astronomy students about a question on the final exam for a cosmology class. It goes like this: “Describe the Universe and give three examples.” Well, a team of researchers in Germany, the U.S., and the UK took a giant leap toward giving at least one accurate example of the Universe.

According to our predominant cosmological models, Dark Matter accounts for roughly 85% of the mass in the Universe. While ongoing efforts to study this mysterious, invisible mass have yielded no direct evidence, astrophysicists have been able to measure its influence by observing Dark Matter Haloes, gravitational lenses, and the effect of General Relativity on large-scale cosmic structures. And with the help of next-generation missions like the ESA’s Euclid and NASA’s Nancy Grace Roman space telescopes, Dark Matter may not be a mystery for much longer!

In its continued support for the Artemis missions, a three fully-electric, environmentally friendly, and specially designed vehicles were recently delivered to NASA for the purpose of ferrying future Artemis astronauts from their crew quarters to historic Launch Pad 39B before their journey to the Moon. The vehicles were built and delivered by Canoo Technologies Inc. based in Torrance, California, and comes just over a year after NASA awarded Canoo the contract to provide the new vehicles, and almost two years since NASA put out a call for proposals.

The cosmic zoo has strange beasts that astronomers stumble across in the most fascinating ways. Not long ago a team in Australia found a highly unusual magnetar, one of the weirder denizens of the starry zoo. It’s called GPM J1839-10 and it lies some 15,000 light-years away in the direction of the constellation Scutum.

Impact craters are nature’s signature from a more chaotic time in our Solar System’s history. A quick glance at the Moon’s disfigured surface makes that clear. Same with Mars, though a telescope is needed to examine it. Or better yet, an orbital spacecraft with a powerful camera.

China’s next-generation crew capsule was given an updated timeline this week. According to Yang Liwei, deputy chief designer of China’s Human Spaceflight Program, the new capsule will make its first flight in 2027 or 2028.  Meeting this timeline will be a key milestone in China’s recently announced plan to land on the Moon by 2030.

Sunlike stars and those smaller than the Sun end their lives as white dwarfs. Without a continued source of energy from hydrogen fusion, these stars eventually collapse under their own weight. They would continue collapsing were it not for the pressure of electrons. As long as the remaining mass of a star is less than about 1.4 Suns, the electron pressure and gravitational pull will balance each other, creating a white dwarf.

The more astronomers look at the early Universe, the more discoveries they make. Some of those finds change what they thought they knew about the infancy of the cosmos. For example, the James Webb Space Telescope (JWST) recently found evidence of carbon-based molecules and dust existing only a billion years after the Big Bang. It looks a bit different from the dust observed later in the Universe.
