If aliens landed on Earth tomorrow, what would they eat?

With the release of "Disclosure Day," Steven Spielberg's new film about aliens, a question as old as science fiction itself resurfaces: If aliens were to arrive on Earth, would they come to conquer us, to study us ... or perhaps to eat?

Astronomers Want to Build a Swarm of Telescopes to Find LIFE

Current plans for flagship telescopes in the 2040s are focused on answering a simple question - are we alone? Our best telescopes to date, such as the James Webb Space Telescope (JWST) have only given us tantalizing glimpses into the atmospheres or other worlds, but not enough to truly determine whether or not life as we know it exists there. Astronomers have been waiting for technology to catch up to their dreams of what is possible in terms of new types of telescopes, and recently the W.M. Keck Institute for Space Studies released a report detailing the Large Interferometer For Exoplanets (LIFE) mission, which they hope will help provide a definitive answer to that simple question.

Lava planet has hydrogen-rich, active atmosphere

It's 2158, and you're chugging away on your Ph.D. in planetary volcanology from the University of Utopia Planitia on Mars. Graduate students still get paid a sub-living wage, so you've been stuck eating freeze-dried ramen for the past three years. You've completed studying Jupiter's moon Io, but now you have to leave the solar system for a good exoplanet analog. While Io's volcanism is caused by tidal heating, you need an exoplanet whose volcanism is caused by extreme heat from its host star. You recently secured funding from the Exoplanet Research Institute for a faster-than-light (FTL) ship, but the exoplanet is required to be less than 50 light-years away.

Famous 'Pink Planet' harbors a salty surprise

Northwestern University-led astronomers have discovered salty skies surrounding the universe's famous "Pink Planet." For more than a decade, the ancient, rosy-hazed world kept astronomers guessing. One of the coldest known planetary-mass companions ever directly imaged, the elusive object is too faint for astronomers to dissect its light from Earth. But new observations from the James Webb Space Telescope (JWST) reveal an atmosphere filled with exotic chemistry—and salty clouds unlike anything seen before.

'High-res' is the secret to finding alien life with the next great space telescope

We're still in the definition phase of the Habitable Worlds Observatory (HWO), but it seems like every week a new research group comes out with a paper helping to shape what is becoming one of the most important space telescopes of the 2040s. A new paper posted to the arXiv preprint server from a team of researchers led by Daniel Jaffe of the University of Texas at Austin contributes to this ongoing definition work by arguing that it's time HWO adopted a high-resolution near-IR spectroscopy capability—which sounds great in practice, but so far hasn't been attempted because of technological limitations. But, according to the paper, two recent inventions finally make a working version of an extremely high-resolution exoplanet hunter viable.

Famous “Pink Planet” harbors a salty surprise

Found in 2013, Pink Planet was too faint to study with ground-based telescopes. In new study, scientists used JWST and advanced processing methods to obtain its spectrum for the first time. Observations provided some of the first direct evidence for salt clouds in a cold object atmosphere. Pink Planet could be a giant planet or brown dwarf, so astronomers refer to it as a ‘planetary-mass companion’.

"3 Reasons Aliens Probably Aren't Visiting Us, According to Science" by @ScienceAlert - So far, science's best guess is the same prohibitive distance, energy and time requirements that prevent us from traveling to other stars, probably also prevents any other life out there from reaching us, if they exist. Any hypothetical civilization advanced enough to do that has no need for anything from Earth, either.

3 Reasons Aliens Probably Aren't Visiting Us, According to Science

The United States government's recent release of hundreds of previously classified Unidentified Anomalous Phenomena (UAPs) cases spanning the 1940s to the present, along with the new Steven Spielberg movie, Disclosure Day, about extraterrestrial life, has fuelled the idea that aliens are visiting Earth.

Oddball exoplanet challenges what it means to be a hot Jupiter

New research led by a scientist at IPAC—a science and data center for astrophysics and planetary science at Caltech—studying the hot Jupiter CoRoT-2 b has settled on one of the three leading hypotheses explaining why its atmosphere has a hot spot in the opposite direction from that seen on all other exoplanets of this type.
