Astronomers Find Dozens of Massive Stars Fleeing the Milky Way
The Milky Way can’t hold onto all of its stars. Some of them get ejected into intergalactic space and spend their lives on an uncertain journey. A team of astronomers took a closer look at the most massive of these runaway stars to see what they could find out how they get ejected. When astronomers…

Between Venus’ atmospheric currents, a layer of reactive oxygen
Today, our sister planet Venus resembles an environment as close to hell as one can imagine. Surface temperatures on the amber world soar to 450 degrees Celsius (842 degrees Fahrenheit), while about 96% of the planet’s crushing atmosphere is made up of carbon dioxide. Once upon a time, however, Venus may have resembled something much…

Milky Way-like galaxy found in the early universe
Using the James Webb Space Telescope, an international team, including astronomer Alexander de la Vega of the University of California, Riverside, has discovered the most distant barred spiral galaxy similar to the Milky Way that has been observed to date. Until now it was believed that barred spiral galaxies like the Milky Way could not…

NASA’s Webb, Hubble Telescopes Combine To Create Most Colorful View Of Universe
Panchromatic view of MACS0416, a galaxy cluster about 4.3 billion light-years from Earth. The image was created by combining infrared observations from NASA’s James Webb Space Telescope with visible-light data from NASA’s Hubble Space Telescope. The resulting prismatic panorama of blues and reds give clues to the distances of the galaxies. NASA, ESA, CSA, STScI,…

James Webb telescope finds an ‘extreme’ glow coming from 90% of the earliest galaxies in the universe
The James Webb Space Telescope (JWST) has discovered that nearly all of the universe’s earliest galaxies were filled with dazzling gas clouds that blazed brighter than the emerging stars within them — and it could help solve a mystery that threatens to break cosmology. Forming as early as 500 million years after the Big Bang,…

SpaceX will launch Ireland’s 1st-ever satellite this month
Ireland is all set to see its first-ever satellite reach orbit. The Educational Irish Research Satellite 1, or EIRSAT-1, was built by University College Dublin students as part of the European Space Agency (ESA) Academy’s Fly Your Satellite! (FYS) program. The gamma-ray astronomy cubesat project began in 2017 and is now due to fly on…

Why we need to bring stellar astrophysics into the real world
Science Photo Library/Alamy RECENTLY, I was giving a tour of the University of New Hampshire’s department of physics and astronomy to a guest who isn’t a scientist. Among the many questions he asked was: “How does this stuff show up in the real world?” The kind of stuff I do, I explained, is mostly just…
