Astronomy

For thousands of years, humanity viewed the skies as unchanging, except for a few “wandering stars” (that we now know are planets). As we improved our ability to perceive the cosmos with light-gathering telescopes and electronic detectors, we realized that the universe is full of things that change in brightness, whether it be an exploding star or a matter-gulping black hole. NASA’s Nancy Grace Roman Space Telescope is poised to deliver an avalanche of such transients, including thousands of “standard candle” supernovae that allow us to measure the expansion history of the universe.

The discovery of an extremely rare quadruple star system could significantly advance our understanding of brown dwarfs, astronomers say. Brown dwarfs in wide binary orbits offer a chance to determine their properties more clearly.

The hunt will be on shortly, to once again recover a clandestine mission in low Earth orbit. SpaceX is set to launch a Falcon-9 rocket from launch pad LC-39A at the Kennedy Space Center Thursday night August 21st, with the classified USSF-36 mission. The U.S. Space Force has announced that this is the eighth mission for its fleet of two Orbital Test Vehicles (OTV-8). This is the automated ‘mini-space shuttle’ about the size of a large SUV that launches like a rocket, and lands like a plane.

Sometimes inspiration can strike from the most unexpected places. It can result in a cross-pollination between ideas commonly used in one field but applied to a completely different one. That might have been the case with a recent paper on lightsail design from researchers at the University of Nottingham that used techniques typically used in video games to develop a new and improved structure of a lightsail.

NASA's Psyche spacecraft, which is headed toward a big and bizarre metal asteroid, has delivered a stunning perspective of our home planet from deep space.

SpaceX scrubbed the planned 10th test flight of its Starship megarocket today (Aug. 24), citing a problem with ground systems at its Starbase site in South Texas.

This galaxy is not only pretty -- it's useful.

A SpaceX cargo ship arrived at the International Space Station on Aug. 25 carrying about 5,000 pounds (2,270 kilograms) of food, supplies and scientific experiments.

If black holes are actually droplets of dark energy that convert stellar matter into this mysterious and dominant force, many "cosmic hiccups" could soon be cured.

How do tidal forces determine a planet’s orbital evolution, specifically planets in the habitable zone? This is what a recently submitted study hopes to address as an international team of researchers investigated how tidal forces far more powerful than experienced on Earth could influence orbital evolution of habitable zone planets with highly eccentric orbits around low-mass stars. This study has the potential to help researchers better understand the formation and evolution of exoplanets, specifically regarding where we could find life beyond Earth.

Some scientists thought that the asteroids Ryugu and Bennu were from the same family. Now that they have samples and JWST spectra from both, the verdict is in: They're both from the Polana collisional family, a diverse and widespread family of asteroids.

Astronomers have discovered what may be a massive star exploding while trying to swallow a black hole companion, offering an explanation for one of the strangest stellar explosions ever seen.
