More images and details keep coming in about the asteroid intentionally smashed by NASA’s Double Asteroid Redirection Test (DART) spacecraft last week, and this latest image is stunning.

NASA and NOAA satellites — as well as astronauts on the ISS — captured some stunning imagery of Hurricane Ian, as seen from orbit. Our lead image shows an eerie view of the hurricane’s eye on September 28. The Landsat 8 satellite passed directly over Ian’s eye as the storm approached southwest Florida.

Ancient impacts played a powerful role in Earth’s complex history. On other Solar System bodies like the Moon or Mercury, the impact history is preserved on their surfaces because there’s nothing to erase it. But Earth’s geologic activity has erased the evidence of impact craters over time, with some help from erosion.

We hope this is just as inconsequential as having a piece of toilet paper stuck to your shoe, but images from the Ingenuity helicopter show it had a piece of debris fluttering from its leg during its most recent flight. A blog post from NASA said a small piece of foreign object debris (FOD) was seen in footage from the Mars helicopter’s navigation camera (Navcam) for a portion of its 33rd flight on September 24, 2022.

Everything dies in the end, even the brightest of stars. In fact, the brightest stars are the ones that live the shortest lives. They consume all the hydrogen they have within a few million years, then explode as brilliant supernovae. Their core remains collapse into a neutron star or black hole. These small, dark objects litter our galaxy, like a cosmic graveyard.

Hubble Space Telescope observes a lot of galaxies. Some of them are wild-looking while others seem fairly placid. Recently, it looked at NGC 5495, which lies about 300 million light-years away from Earth. You wouldn’t know just by looking at it, but this galaxy has some pretty hot action happening in its core.

“Go then, there are other worlds than these.” Or so Stephen King said in his famous Dark Tower series. As of yet, none of those worlds are known to be like Earth. But, according to some new simulations by researchers at the National Astronomical Observatory of Japan (NAOJ), finding a genuinely Earth-like world might be in the cards by the decade’s end.

Radio astronomy has been in flux lately. With the permanent loss of the Arecibo telescope in Puerto Rico, a new global power has taken center stage in humanity’s search for radio signals – China. Recently the Chinese announced the start of work on a new milestone telescope, which will eventually make it the biggest moveable one in the world.

NASA’s Mars Sample Return Mission is inching closer and closer. The overall mission architecture just hit a new milestone when Perseverance collected the first sample that will be sent back. But what happens once that sample actually gets here? NASA and its partner, ESA, are still working on that, but recently they released a fact sheet that covers what will happen during the first stage of that process – returning to the ground.

In June 2027, NASA will launch the long-awaited Dragonfly mission toward Saturn’s largest moon, Titan. By 2034, the 450 kg (990-lbs) nuclear-powered quadcopter will touch down at its target landing site (the Selk crater region) and begin searching Titan’s surface and atmosphere to learn more about this curious satellite. In particular, the mission will investigate the moon’s prebiotic chemistry, active methane cycle, and organic environment. These goals underpin Dragonfly’s main objective, which is to search for possible signs of life (aka. “biosignatures”) on Titan.

Humanity moved an asteroid on purpose for the first time in history. Juno flies past Jupiter’s moon Europa. A possible mission to boost Hubble, and a mysterious blob is orbiting Milky Way’s supermassive black hole.

In a recent study published in Monthly Notices of the Royal Astronomical Society, an international team of researchers led by Stanford University have produced the first computer-generated 3D model of the Cat’s Eye Nebula, which unveiled a symmetric pair of rings that enclose the outer shell of the nebula. This study holds the potential for helping us better understanding the nebula’s makeup and how it formed, as the symmetric rings provides clues that they were formed from a precessing jet, which produces strong confirmation that a binary star exists at the nebula’s center.

We recently examined how and why Jupiter’s moon, Europa, could answer the longstanding question: Are we alone? While this small icy world gives plenty of reasons to believe why we could—and should—find life within its watery depths, it turns out our solar system is home to a myriad of places where we might find life. Much like how the Voyager missions gave us the first hints of an interior ocean swirling beneath Europa’s outer icy shell, it was only fitting that Voyager 1 also gave us the first hints of the potential for life on Saturn’s largest moon, Titan, as well.

Mars exploration has been ongoing for decades at this point, and some regions of the planet have become more interesting than others. Of particular interest is a basin known as Utopia Planitia. It was the site of the Viking-2 landing, one of the first-ever successful missions to Mars. From data collected during that mission, scientists developed a theory that the crater that formed Utopia might have been the site of an ancient ocean. New results from China’s Zhurong rover point to an even more exciting past – repeated flooding.

Kessler syndrome seems to be a growing fear for those interested in space exploration. The condition where numerous non-functional pieces of junk block access to orbit appears to be inching closer to reality, spurred on by weekly news reports of dozens of more satellites launching that will eventually become precisely that kind of obsolete space junk. But that won’t happen if the US’s Federal Communications Commission (FCC) has anything to do with it – a new rule the commission adopted will require companies to deorbit their unused satellites in less than five years after decommissioning.

3D printing will be an absolutely critical technology as space exploration starts to take off. Initially, it will be impossible to individually manufacture every tool needed to create and sustain infrastructure in space. The only option will be to build some of those tools in space itself, in no small part, because it could potentially take months or even years to get to any area where the tools are manufactured. So any tool that can be created in situ is the best option available for early space explorers. Using materials like Martian regolith to 3D print those tools has long been an area of ongoing research. Now a team from Washington State University has successfully printed some tools using simulated Martian regolith, and they seem to work – up to a point.

There’s a star system out there with three super-Earth planets and two super-Mercuries. Super-Earths are fairly familiar types of exoplanets, but super-Mercuries are rare. Those are planets with the same composition as our own Mercury, but larger and denser. Yet, here’s HD 23472, showing off two of eight known super-Mercuries in the galaxy.

Astronomers have been assessing a new machine learning algorithm to determine how reliable it is for finding gravitational lenses hidden in images from all sky surveys. This type of AI was used to find about 5,000 potential gravitational lenses, which needed to be confirmed. Using spectroscopy for confirmation, the international team has now determined the technique has a whopping 88% success rate, which means this new tool could be used to find thousands more of these magical quirks of physics.

Here’s a sharper view of Dimorphos, the small asteroid moonlet that the DART (Double Asteroid Redirection Test) spacecraft intentionally crashed into. Eydeet on Imgur created a higher resolution image of Dimorphos by stacking the last few images received from the spacecraft before impact.

When you imagine the collision of galaxies, you probably think of something violent and transformational. Spiral arms ripped apart, stars colliding, cats and dogs living together, mass hysteria. The reality is much less dramatic. As a recent study shows, our galaxy is in a collision right now.

Astronomers studying a stellar cluster within the Small Magellanic Cloud (SMC) have found young stars spiraling in towards the center of the cluster. The cluster, NGC 346, is an open cluster embedded within a glowing cloud of gas, which is typical of stellar nurseries – places where new stars are formed. The outer spiral arm of this star forming region appears to be funneling gas, dust and new stars into the center, which researchers describe as an efficient way to fuel the birth of new stars.
