Two new exoplanets and the need for new habitable zone definitions

At the beginning of the exoplanet age, the goals were fairly simple. The first was to find as many of them as possible to flesh out our understanding of the exoplanet population. The second was to determine if any were in the habitable zones around their stars.

Peering below Callisto’s icy crust with ALMA

What exists beneath the surface of Jupiter’s icy moon, Callisto? This is what a recent study accepted by The Planetary Science Journal hopes to address as a team of researchers investigated the subsurface composition of Callisto, which is Jupiter’s outermost Galilean satellite. This study has the potential to help scientists better understand the interior composition […]

Researchers solve mystery of universe’s ‘little red dots’

Since the James Webb Space Telescope (JWST) went into operation, red dots in its images have puzzled researchers around the world. Now, researchers from the University of Copenhagen have explained these enigmatic findings, revealing the most violent forces in the universe concealed in a cocoon of ionized gas. The discovery is published in Nature.

A ‘cosmic clock’ in tiny crystals reveals the rise and fall of Australia’s ancient landscapes

Australia’s iconic red landscapes have been home to Aboriginal culture and recorded in songlines for tens of thousands of years. But further clues to just how ancient this landscape is come from far beyond Earth: cosmic rays that leave telltale fingerprints inside minerals at Earth’s surface.

Astronomers discover 19 new pulsars by analyzing FAST archival data

Astronomers from Nanjing University in China have analyzed the archival data from the Five-hundred-meter Aperture Spherical radio Telescope (FAST), searching for new pulsars. As a result, they detected 19 such objects that were missed by previous studies. The findings were presented January 5 on the pre-print server arXiv.

Siwarha’s wake gives it away at Betelgeuse

Betelgeuse is the star that everybody can’t wait to see blow up, preferably sooner rather than later. That’s because it’s a red supergiant on the verge of becoming a supernova and there hasn’t been one explode this close in recorded human history. It’s been changing its brightness and showing strange surface behavior, which is why […]

Can philanthropy fast-track a flagship telescope?

New Space is a term now commonly used around the rocketry and satellite industries to indicate a new, speed focused model of development that takes its cue from the Silicon Valley mindset of “move fast and (hopefully don’t) break things.” Given that several of the founders of rocketry and satellite companies have a Silicon Valley […]
