Stellar Evolution Code “METISSE” Offers New Insights Into the Lives of Massive Stars
Massive stars are larger than about 10 times the mass of the Sun and are born far less often than their low mass counterparts. However,…

A permeable heart with a hardened facade — the resting place of Rosetta’s lander on Comet 67P/Churyumov-Gerasimenko is revealing more about the interior of the…
Humanity has “eyes” that can detect all different types of light through telescopes around the globe and a fleet of observatories in space. From radio…
Episode 2: An Unexpected Journey – With five servicing missions, upgraded instruments, and new ways of operating, Hubble is not the same telescope it was…
Many colorful stars are packed close together in this image of the globular cluster NGC 1805, taken by the NASA/ESA Hubble Space Telescope. This tight…
In atomic nuclei, protons and neutrons share energy and momentum in tight quarters. But exactly how they share the energy that keeps them bound within…
Researchers suggest a novel process to explain the collision of a large black hole and a much smaller one. A lopsided merger of two black…
The Nancy Grace Roman Space Telescope’s primary mirror, which will collect and focus light from cosmic objects near and far, has been completed. Using this…
The process occurs in active-core nuclei. A molecular gas cloud that accumulates in the central region is blown away by radiation from the black hole’s…
A binary black hole merger likely produced gravitational waves equal to the energy of eight suns. For all its vast emptiness, the universe is humming…
A team of astronomers have identified the first direct evidence that groups of stars can tear apart their planet-forming disc, leaving it warped and with…
What’s Up for September? The Moon with Mars and Venus, and a star with a planet…that wasn’t. On September 6th, you’ll find the Moon extremely…
The unexpected findings were a result of data collected for more than a decade at the NSF facility, which is managed by the University of…
Astronomers have known for two decades that the expansion of the universe is accelerating, but the physics of this expansion remains a mystery. Now, a…
Scientists Detect First-of-Its-Kind ‘Intermediate-Mass’ Black Hole An international research collaboration including Northwestern University astronomers has witnessed the birth of an “intermediate-mass” black hole. This is…
A new theory published recently in The Astrophysical Journal Letters by scientists from Harvard University suggests that the Sun may once have had a binary…
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a census of stellar eggs in the constellation Taurus and revealed their evolution state. This census…
Radio astronomers have detected jets of hot gas blasted out by a black hole in the galaxy at the heart of the Phoenix Galaxy Cluster,…
