The Snows of Churyumov-Gerasimenko

 

You couldn't really be caught in this blizzard while standing by a cliff on periodic comet 67P/Churyumov-Gerasimenko. Orbiting the comet in June of 2016, the Rosetta spacecraft's narrow angle camera did record streaks of dust and ice particles similar to snow as they drifted across the field of view close to the camera and above the comet's surface. Still, some of the bright specks in the scene are likely due to a rain of energetic charged particles or cosmic rays hitting the camera, and the dense background of stars in the direction of the constellation of the Big Dog (Canis Major). In the video, the background stars are easy to spot trailing from top to bottom. The stunning movie was constructed from 33 consecutive images taken over 25 minutes while Rosetta cruised some 13 kilometers from the comet's nucleus. In September 2016, the nucleus became the final resting place for the Rosetta spacecraft after its mission was ended with a successful controlled impact on 67P/Churyumov-Gerasimenko.

The 'Super Bowl of Astronomy' begins next week in New Orleans

Jan 5, 2024

 

The world of astronomy has already offered a pretty fascinating start to 2024. In just the first five days of the year, we've seen incredible discoveries like the true colors of Neptune and Uranus as well as a massive cyclone raging on a distant exoplanet thanks to the trusty Hubble Space Telescope. But things are only going to ramp up over the next week. By a lot.

 

From Jan. 7 to Jan. 11, the 243rd meeting of the American Astronomical Society will convene in the vibrant city of New Orleans, Louisiana.

 

Thousands of scientists specializing in an absolutely incredible array of subjects ranging from dark matter mysteries to star explosions and the search for habitable exoplanets to the technology required to propel spacecraft across the solar system will gather in one area. They'll get ready to announce some of the best and brightest studies they've been working on; meanwhile, they'll be figuring out how to get even bigger and brighter with their next by listening to wild ideas, strange contradictions and telescopic achievements their colleagues will lay out. Some have even called this event the "Super Bowl of Astronomy."

 

NASA will be there too, to offer updates on major missions like the trailblazing, $10 billion James Webb Space Telescope and the upcoming, highly anticipated, Habitable Worlds Observatory. According to a statement released on Jan. 5, NASA will also be discussing the 2024 total solar eclipse, which will take place on April 8, the Transiting Exoplanet Survey Satellite (TESS), the Nancy Grace Roman Telescope currently under construction and even its scientific balloon program.

 

"Experts will discuss new research from NASA missions at the 243rd meeting of the American Astronomical Society (AAS) on topics ranging from planets outside our solar system to fleeting, high-energy explosions in the universe," the agency said in the statement.

 

All NASA press conferences will be streamed for the public to view on AAS's Press Office YouTube channel; other conferences during the meeting will be found there as well. After the meeting concludes, the streams will be available to view on an online archive provided by the organization. You'll notice that this archive includes a wealth of presentations from previous years as well.

 

Beyond NASA, teams from other iconic space facilities, current and upcoming, are scheduled to speak, too. Members of the Rubin Observatory, for instance, are expected to let everyone know how things are going with their efforts to discover tens of billions of galaxies once its construction is complete in Chile. But, as we'd mentioned, perhaps the most interesting and hopefully mind-blowing presentations will be coming from researchers speaking during the event.

 

Though we don't have a ton of information yet on each of those talks, we're able to see some of the study headlines. And they look quite intriguing. For instance, Jan. 8 is poised to bring us an update on a "dark galaxy," the origins of "odd radio circles," and a "famous exploded star in its best light." Jan. 9 appears to have information concerning an exoplanet's tail-like escaping atmosphere and a highly distant fast radio burst seen by the Hubble Space Telescope. Jan. 10 has something about a "supernova imposter" on its schedule and Jan. 11 beholds an entire category of presentation dubbed "Oddities in the Sky." This honestly barely scratches the surface.
