Omega Centauri dominates the southern sky as the Milky Way’s largest and brightest globular cluster, a dense sphere containing roughly 10 million stars. Earlier this year, astronomers found evidence that an intermediate mass black hole […]

On July 1st, 2025, the third interstellar object (ISO) ever detected was seen making its way through our solar system. Shortly after being alerted by automated detection systems, astronomers at the European Space Agency (ESA) […]

NASA’s Hubble Space Telescope captured an uncommon sight—the death of a low-mass star—in this image of the Calabash Nebula released on Feb. 3, 2017.This post was originally published on this site

Astronomers from the University of Hawai’i (UH) at Manoa and elsewhere have observed the Taurus star-forming region, which resulted in the discovery of planetary-mass and stellar companions of two ultracool dwarf stars. The new finding […]

The first exoplanet ever discovered in 1995 was what we now call a “hot Jupiter,” a planet as massive as Jupiter with an orbital period of just a few days. Today, hot Jupiters are thought […]

One of the oldest unsolved riddles in planetary science concerns the origin of the moon. Over a century ago, George Darwin proposed that tidal and centrifugal forces on a rapidly rotating proto-Earth caused the moon […]

What could force a supermassive black hole (SMBH) out of its host galaxy? They can have hundreds of millions, even billions of solar masses. What’s powerful enough to dislodge one of these behemoths?This post was […]

The Large and Small Magellanic Clouds are irregular dwarf galaxies and satellites of the Milky Way. The LMC is about 163,000 light-years away and the SMC is about 206,000 light-years away, and their close proximity […]

A research team has investigated long-term X-ray variability in the neutron star NGC 7793 P13, an object thought to be driven by supercritical accretion, where an extraordinary amount of gas falls onto the object and […]

Images captured by NASA’s Parker Solar Probe as the spacecraft made its record-breaking closest approach to the sun in December 2024 have now revealed new details about how solar magnetic fields responsible for space weather […]
