The universe is about 13.8 billion years old, and its stars are arguably its most momentous handiwork. Astronomers studying the intricacies of star formation across…
The end of a star’s life can occur in a tranquil manner in the case of low-mass stars, such as the Sun. This is not…
An international consortium of scientists studying gamma-ray bursts (GRBs) as part of the POLAR (GRB polarimeter) experiment has revealed that high-energy photon emissions from black…
New research that included astronomers Luca Matra and David J. Wilner of the Harvard-Smithsonian Center For Astrophysics has found the first confirmed example of a…
Astronomers have discovered behavior by a jet from a giant black hole that has never been seen before. Using NASA’s Chandra X-ray Observatory they have…
Data captured by ESA’s galaxy-mapping spacecraft Gaia has revealed for the first time how white dwarfs, the dead remnants of stars like our Sun, turn…
Many stars explode as luminous supernovae when, swollen with age, they run out of fuel for nuclear fusion. But some stars can go supernova simply…
Pulse pattern suggests distant black hole must be spinning at least at 50 percent the speed of light. On November 22, 2014, astronomers spotted a…
A brief and unusual flash spotted in the night sky on June 16, 2018, puzzled astronomers and astrophysicists across the globe. The event — called…
Researchers have discovered the brightest quasar yet known, detected from the period when the universe’s star-making hydrogen gas became ionized, known as “reionization.” The international…
Galaxy mergers—in which two galaxies join together over billions of years in sometimes-dramatic bursts of light—aren’t always easy for astronomers to spot. Now, scientists from…
The stellar wind from a newborn star in the Orion Nebula is preventing more new stars from forming nearby, according to new research using NASA’s…
Scientists have found evidence that dark matter can be heated up and moved around, as a result of star formation in galaxies. The findings provide…
New research led by astrophysicists at Durham University, UK, predicts that the Large Magellanic Cloud (LMC) could hit the Milky Way in two billion years’…
NASA’s New Horizons spacecraft flew past Ultima Thule in the early hours of New Year’s Day, ushering in the era of exploration from the enigmatic…
At 2:43 p.m. EST on December 31, while many on Earth prepared to welcome the New Year, NASA’s OSIRIS-REx spacecraft, 70 million miles (110 million…
