Some binary stars are unusual. They contain a main sequence star like our Sun, while the other is a “dead” white dwarf star that left fusion behind and emanates only residual heat. When the main sequence star ages into a red giant, the two stars share a common envelope.

Supermassive black holes bent the laws of physics to grow to monstrous sizes
Scientists may have cracked one of the biggest mysteries in space science, determining that supermassive black holes bent the laws of physics to grow to their huge sizes.
What a Misplaced Meteorite Told Us About Mars
11 million years ago, Mars was a frigid, dry, dead world, just like it is now. Something slammed into the unfortunate planet, sending debris into space. A piece of that debris made it to Earth, found its way into a drawer at Purdue University, and then was subsequently forgotten about.
The not so 'wicked' path from 'The Wizard of Oz' to the moon landing
"The Wizard of Oz" and space exploration are two topics that by all rights should have nothing in common. But as it turns out, if you follow the Yellow Brick Road long enough you reach the moon.

Did NASA's Perseverance rover really find organics on Mars? These scientists aren't so sure
Could Mars have once hosted life? NASA's Perseverance rover has uncovered a tantalizing clue, but scientists remain divided on what it truly means for the search for extraterrestrial life.
'There are lots of mysteries in our backyard': Revised solar system chemistry explains long-standing puzzles
Pluto and other large bodies in the Kuiper Belt are surprisingly rich in rock rather than ice. It may be because the early solar system consisted of much more carbon than previously thought, a new study suggests.
Uranus is Getting Colder and Now We Know Why
Uranus is an oddball among the Solar System’s planets. While most planets’ axis of rotation is perpendicular to their orbital plane, Uranus has an extreme tilt angle of 98 degrees. It’s flopped over on its side, likely from an ancient collision. It also has a retrograde orbit, opposite of the other planets.
ISS fires thrusters to dodge hunk of space junk
A Russian cargo ship docked to the International Space Station fired its thrusters on Tuesday (Nov. 19) to ensure that the orbiting complex dodged a piece of space debris.
Somewhere in the multiverse, dark energy is helping stars and life form
The strength of dark energy in our universe is not optimized for forming stars, which means other universes might have a greater likelihood of producing life.

'Superhighways' connecting the cosmic web could unlock secrets about dark matter
Giant filaments crisscross the universe, connecting galaxy clusters like superhighways between cities. But due to their complex shapes, they are stubbornly difficult to measure.
SpIRIT CubeSat Demonstrates a Operational Gamma and X-Ray Detector
CubeSats are becoming more and more capable, and it seems like every month, another CubeSat is launched doing something new and novel. So far, technology demonstration has been one of the primary goals of those missions, though the industry is moving into playing an active role in scientific discovery. However, there are still some hurdles to jump before CubeSats have as many scientific tools at their disposal as larger satellites. That is where the Space Industry Responsive Intelligent Thermal (SpIRIT) CubeSat, the first from the Univeristy of Melbourne’s Space Lab, hopes to make an impact. Late in 2023, it launched with a few novel systems to operate new scientific equipment, and its leaders published a paper a few months ago detailing the progress of its mission so far.
Sun-Like Stars Around Black Holes: What Gives?
Buried in the treasure trove of the Gaia catalog were two strange black hole systems. These were black holes orbiting sun-like stars, a situation that astronomers long thought impossible. Recently a team has proposed a mechanism for creating these kinds of oddballs.
