Andromeda, The Galaxy That Will Collide With The Milky Way, Is Already Visible To The Naked Eye In The Sky

Andromeda is on a collision course with our galaxy. Now begins the best time of year to capture it with the naked eye. This is what Andromeda galaxy will look like in the night sky if it were brighter. Our galaxy, the Milky Way, and its neighbor twice its size, Andromeda, are on a collision course. Both are approaching each other at a speed of 113 kilometers per second due to gravitational pull, and although they are expected to collide in 4.5 billion years, their outer layers have already begun to merge . Meanwhile, people on Earth have the opportunity to observe Andromeda, also known as Messier 31 , with the naked eye. From mid-August to November, the spiral galaxy appears in the night sky of both hemispheres of our planet. Despite being located 2.5 million light-years away, Andromeda occupies a quarter of a degree in the sky. This is equal to half the width of a full moon, according to NASA. When will the Andromeda galaxy be visible? Due to its remoteness, Andromeda has a diffuse

Scientists Watched a Star Explode in Real Time for The First Time Ever

Astronomers have watched a giant star blow up in a fiery supernova for the first time ever — and the spectacle was even more explosive than the researchers anticipated. Scientists began watching the doomed star — a red supergiant named SN 2020tlf and located about 120 million light-years from Earth — more than 100 days before its final, violent collapse, according to a new study published Jan. 6 in the Astrophysical Journal. During that lead-up, the researchers saw the star erupt with bright flashes of light as great globs of gas exploded out of the star's surface. These pre-supernova pyrotechnics came as a big surprise, as previous observations of red supergiants about to blow their tops showed no traces of violent emissions, the researchers said. "This is a breakthrough in our understanding of what massive stars do moments before they die," lead study author Wynn Jacobson-Galán, a research fellow at the University of California, Berkeley said in a statement. "For

NASA's $10 billion Telescope has just captured its first direct unbelievable image of a Planet outside our Solar system

The James Webb Space Telescope has captured the first direct image of a distant exoplanet, a world beyond our Solar System. Webb has returned several pictures of the exoplanet HIP 65426 b, a gas giant six to twelve times the mass of Jupiter located roughly 385 light years from Earth, using a range of instruments. The James Webb Space Telescope captured this image of the exoplanet HIP 65426 b. (Nasa) The findings are part of an ongoing investigation and have not yet been peer-reviewed or published in a scientific journal, but Nasa announced them in a blog post Thursday morning. "This is a pivotal moment, not only for Webb but also for astronomy in general," said Sasha Hinkley, associate professor of physics and astronomy at the University of Exeter. She is the principal scientist in an international team studying exoplanets. HIP 65426 b was discovered in 2017 by the European Southern Observatory's Very Large Telescope in Chile, which observed the exoplanet in short wavelen
