Astronomers using the Hubble Space Telescope have observed 3I/ATLAS, only the third known object from outside our Solar System to visit our neighborhood. This interstellar interloper is putting on quite a show as it approaches the Sun, revealing secrets about visitors from the depths of space. 3I/ATLAS is clearly active at 3.8 astronomical units as it approaches the Sun, showing …

In a groundbreaking study published in the Journal of Vertebrate Paleontology, an international team of paleontologists has uncovered a rich treasure trove of Permian fossils from southern Africa. These fossils, excavated over 15 years, offer unprecedented insights into the life forms that inhabited Earth just before the planet’s largest mass extinction, known as the Great Dying. This extinction event occurred …

An astrophysicist has made an ambitious proposal for how humanity could probe the extreme physics of black holes — by sending a spaceship no bigger than a paperclip to our nearest one. The spacecraft, no heavier than a gram and propelled to a third of the speed of light by lasers on Earth, would gather information on a nearby space-time …

Astronomers have discovered what could be the largest black hole ever detected. With a mass of 36 billion times that of our Sun, its gravity is so powerful that it bends the light of an entire galaxy behind it into a near-perfect circle called an Einstein ring, effectively reducing a realm with trillions of stars of its own into an …

United Launch Alliance fired off its first operational Vulcan rocket Tuesday, boosting two military satellites into space in the first U.S. Space Force-sanctioned flight of a new launcher that eventually will replace the company’s Atlas 5 and already-retired Deltas. Equipped with four solid-fuel strap-on boosters for additional takeoff power, the 198-foot-tall Vulcan’s two methane-fueled BE-4 engines thundered to life at …

United Launch Alliance’s Vulcan rocket roared off the pad at Space Launch Complex 41 to begin the USSF-106 mission for the U.S. Space Force. This was the first national security launch using a Vulcan rocket and the 101st national security mission for ULA.

In a recent study published in Nature Climate Change, scientists explored the changing dynamics of the Antarctic phytoplankton communities over a span of nearly three decades. The comprehensive research, led by Dr. Alexander Hayward of the Danish Meteorological Institute, paints a worrying picture of a fundamental transformation in one of the most sensitive and important ecosystems on the planet. The …
