2 black holes collided billions of years ago. The spectacle is just beginning to reach Earth.

In a galaxy far, far away, two giant black holes appear to be circling each other like fighters in a galactic boxing ring. Gravity is causing this death spiral, which will result in a collision and formation of a single black hole, a massive event that will send ripples through space and time.  The collision itself happened eons ago — the two black holes are located about 9 … Continue reading 2 black holes collided billions of years ago.

Hawaiian scientists discover one of the youngest planets ever seen

An international research team led by the University of Hawaiʻi at Mānoa has discovered one of the youngest planets ever observed. The findings, published in Monthly Notices of the Royal Astronomical Society, estimate the planet is a “few times more massive” than Jupiter. The new planet was found in a “stellar nursery” and formed approximately several million years ago — around the same time that the … Continue reading Hawaiian scientists discover one of the youngest planets ever seen

Massive comet as large as small planet barreling toward our solar system

A massive comet — so large that scientists had previously mistaken it for a dwarf planet — is hurtling through space toward our solar system and is expected to arrive in about 10 years, new research revealed. The Bernardinelli-Bernstein comet is an estimated to be 60-120 miles across, 1,000 times larger than a traditional comet, astronomers said when its discovery was first announced in June. It … Continue reading Massive comet as large as small planet barreling toward our solar system

Spacecraft snaps closest pictures of sun, ‘campfires’ abound

A European and NASA spacecraft has snapped the closest pictures ever taken of the sun, revealing countless little “campfires” flaring everywhere. Scientists on Thursday released the first images taken by Solar Orbiter, launched from Cape Canaveral in February. The orbiter was about 48 million miles (77 million kilometers) from the sun — about halfway between Earth and the sun — when it took the stunning … Continue reading Spacecraft snaps closest pictures of sun, ‘campfires’ abound
