It’s a classic tale of apocalyptic fiction. The Sun, our precious source of heat and light, collapses into a black hole. Or perhaps a stray black hole comes along and swallows it up. The End is Nigh! If a stellar-mass black hole swallowed our Sun, then we’d only have about 8 minutes before, as the kids say, it gets real. But suppose the Sun swallowed a small primordial black hole? Then things get interesting, and that’s definitely worth a paper on the arXiv.

SpaceX is now targeting Dec. 28 for the launch of the U.S. Space Force's X-37B space plane atop a Falcon Heavy rocket, after a delay of more than two weeks.
How the songs of stars can help perfect Gaia's sweeping map of our galaxy
By listening to "music" played by shaking stars, astronomers could use asteroseismology as a new type of cosmic distance ruler, perfecting the 3D map of two billion stars being built by Gaia.
World's best space-based thermometer dead 2 months after 1st image release
The world's most accurate space-based thermometer has suffered a mission-critical anomaly only two months after the release of its first images.

Hubble Sees a Random Collection of Galaxies, Perfectly Lined Up
This new image from the Hubble Space Telescope looks like a series of smaller spiral galaxies are falling out of a larger and brighter galaxy. That’s just one of the many reasons this collection of galaxies belongs to the Arp-Madore catalogue of peculiar galaxies.
This ISS mission could 'open some eyes' about climate science
A first-of-its-kind mineral map delivered by the NASA International Space Station mission, EMIT, will present big-picture climate science and "open some eyes."
Photonic Crystals Could Be Exactly What Breakthrough Starshot is Looking For
Light sail technology is a fascinating concept and a step change in rocket propulsion. It may not be big and impressive like the Saturn V, the Space Shuttle or the new Starship rocket but when it comes to travelling among the stars, light sails could just be the answer. And what better material to build the sails from then something that just makes me want to say it over and over again….I talk about photonics crystals. It’s sounds right out of a Star Trek episode but a new paper examines their feasibility.
17 Known Exoplanets Could Have Oceans of Liquid Water
The search for life is tied to the search for liquid water. That’s why astronomers are so keen on detecting rocky, Earth-like exoplanets in their stars’ habitable zones. In a habitable zone, a planet receives enough energy from its star to maintain liquid water on its surface, given the right atmospheric conditions.
Perseverance Mars rover to climb crater rim next spring in bonus mission
NASA's Perseverance rover has been exploring Mars' Jezero Crater for nearly three years, but it will soon move on to investigate a vastly different environment.
What’s the Source of Binary Rogue Planets?
The James Webb Space Telescope (JWST) is already making great strides in helping us to unravel the mysteries of the Universe. Earlier this year, hundreds of rogue planets were discovered in the Orion Nebula. The real surprise to this discovery was that 9% of the planets were paired up in wide binary pairs. To understand how this binary planets formed, astronomers simulated various scenarios for their formation.
Ancient Stars Could Make Elements With More Than 260 Protons
The first stars of the Universe were monstrous beasts. Comprised only of hydrogen and helium, they could be 300 times more massive than the Sun. Within them, the first of the heavier elements were formed, then cast off into the cosmos at the end of their short lives. They were the seeds of all the stars and planets we see today. A new study suggests these ancient progenitors created more than just the natural elements.
