Name someone who at some point in their life didn’t want to be an astronaut. The answer is no one. Ask any kid what they want to be when they grow up and they all say an astronaut. Being an astronaut is the ultimate dream job for everyone of all ages. Why? Because you get to go to space, and there’s nothing cooler than going into space. For context, even if you’re not a sports fan you have watched the Super Bowl at least once in your life. It is one of the most watched and most lauded sports championship games in the entire world, and yet despite all its media attention and halftime shows and all-time great finishes, the Super Bowl still holds a candle to being able to go to space. Eat your heart out, Tom Brady. Going into space is just awesome, and there’s nothing like it.

Collapsing ice shelves on the eastern coast of Antarctica has revealed something never seen before: a landform that might be an island. But this is not the first newly revealed island off the Antarctic coast. A series of islands have appeared as the ice shelves along the continent’s coastline has disintegrated over the past few years.

Sometime in the next couple of decades, humans will head to Mars for long-term missions of more than 400 days. Such lengthy stays mean building Martian cities, complete with safe habitats, labs, and other infrastructure. Future Martians will have to do a lot to survive. They’ll build their cities, make their own food, distill water, create fuel, manufacture medicines, and create other supplies. To do that, they’ll use manufacturing facilities that they bring along. That all requires power. Lots of it. As we all know, Mars is noticeably lacking in obvious ways to make electricity. So, what will our intrepid explorers do to generate power for their new lives on the Red Planet?

Saturn’s largest moon, Titan, is a fascinating and mysterious world, a world literally shrouded in mystery due to thick clouds that cameras imaging in the visible spectrum cannot penetrate. This was made apparent when NASA’s Pioneer 11 became the first spacecraft to fly past Titan in 1979, and then NASA’s Voyager 1 and 2 in 1980 and 1981, respectively. All three spacecraft were equipped with cameras that were unable to penetrate Titan’s atmosphere of thick clouds, although atmospheric data from Voyager 1 suggested Titan might be the first body, aside from Earth, where liquid might exist on its surface.

The most energetic explosions in the Universe come from stars called supernovae. These galactic bombs have the energy of about 1028 mega-tons. After they detonate, the only thing left behind is either a neutron star or black hole. Another type of stellar explosion is known as a nova which has much less energy and covers the surface of a white dwarf.

If the phrase “My god, it’s full of stars” was ever appropriate, it’s due to these new images from the James Webb Space Telescope. These are ‘just’ engineering images, mind you, but they are incredible. The number of stars and galaxies visible in each image is just remarkable, not to mention the crisp clarity in the fields of view.

You may recall we reported earlier this month that the Perseverance rover finally spotted its parachute and backshell off in the distance. This is the hardware that safely brought the rover to Mars surface on February 18, 2021.

What is that large dark smudge on Jupiter’s side? It may remind you of a certain scene from the sci-fi film “2010: The Year We Make Contact,” where a growing black spot appears in Jupiter’s atmosphere.

A remote solar eclipse this coming weekend sets us up for the first total lunar eclipse of 2022.

At the heart of the more massive galaxies in the Universe, there are supermassive black holes (SMBHs) so powerful that they outshine all of the stars in their galactic disks. The core regions of these galaxies are known as Active Galactic Nuclei (AGN), or by their more popular-moniker “quasars.” The ongoing study of these objects has provided a testbed for General Relativity and revealed a great deal about the formation and evolution of galaxies and the large-scale structure of the Universe.

On Earth, all life comes down to the polymeric molecules known as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). These two building blocks contain all of the instructions for every living organism and its many operations. In turn, these are made up of five informational components (nucleobases), which are composed of organic molecules (purines and pyrimidines). For decades, scientists have been scouring meteorite samples for these building blocks.

Hot Jupiters are giant exoplanets – even more massive than Jupiter – but they orbit closer to their star than Mercury. When they were first discovered, hot Jupiters were considered oddballs, since we don’t have anything like them in our own Solar System. But they appear to be common in our galaxy. As exoplanets go, they are fairly easy to detect, but because we don’t have up-close experience with them, there are still many unknowns.

Beneath the surface of Jupiter’s icy moon Europa, there’s an ocean up to 100 km (62 mi) deep that has two to three times the volume of every ocean on Earth combined. Even more exciting is how this ocean is subject to hydrothermal activity, which means it may have all the necessary ingredients for life. Because of this, Europa is considered one of the most likely places for extraterrestrial life (beyond Mars). Hence, mission planners and astrobiologists are eager to send a mission there to study it closer.

NASA has granted mission extensions to eight different planetary missions, citing the continued excellent operations of the spacecraft, but more importantly, the sustained scientific productivity of these missions, “and the potential to deepen our knowledge and understanding of the solar system and beyond.” Each mission will be extended for three more years.

The famous Russian rocket scientist Konstantin Tsiolkovsky once said, “Earth is the cradle of humanity, but one cannot remain in the cradle forever.” Tsiolkovsky is often hailed as one of the fathers of rocketry and cosmonautics and remembered for believing in the dominance of humanity throughout space, also known as anthropocosmism. His work in the late-19th and early-20th centuries helped shape space exploration several decades before humanity first walked on the Moon.

Europe’s Large Hadron Collider has started up its proton beams again at unprecedented energy levels after going through a three-year shutdown for maintenance and upgrades.

The Drake equation is one of the most famous equations in astronomy.  It has been endlessly debated since it was first posited in 1961 by Frank Drake, but so far has served as an effective baseline for discussion about how much life might be spread throughout the galaxy.  However, all equations can be improved, and a team of astrobiologists and astronomers think they have found a way to do so.  

Axiom Space’s first crew of private astronauts is back on Earth after a 17-day orbital trip that included a week of bonus time on the International Space Station. The mission ended at 1:06 p.m. ET (5:06 p.m. GMT) today when SpaceX’s Crew Dragon Endeavour splashed down in the Atlantic Ocean off the coast of Florida.

NASA’s Lucy spacecraft, currently on its way to the outer Solar System to study Jupiter’s Trojan asteroids, has a solar panel problem. Shortly after its launch last October, engineers determined that one of Lucy’s two solar panels failed to open completely. While the spacecraft has enough power to function, the team is concerned about how the unlatched panel might hinder Lucy’s performance going forward. In an attempt to fix the problem, the team will carry out a new procedure next month that is designed to unfurl the solar panel the rest of the way, and latch it firmly in place.

While the Hubble Space Telescope celebrates 32 years in orbit, like a fine wine, it has only gotten better with age as it continues to study the Universe and teach us more about our place in the cosmos. Hubble doesn’t just take breathtaking images of our Universe, but it also studies our own solar system, galaxies, and exoplanets, as well. It is this last subject where Hubble has recently been hard at work, though.
