A survey of the residual light in the night sky has uncovered an eerie, omnipresent glow spread throughout the Solar System, thought to be caused by sunlight reflected from cometary dust. Over its 30-plus years of operations, astronomers have become accustomed to subtracting the background light from the Solar System from Hubble’s images. They are ...
When a star explodes (a supernova), it sends its intense burst of light out in all directions that have been captured in telescope images. However, on rare occasions, in the months and years that follow, rings of light or “light echoes” spread out from the original supernova position. This is described in a recent paper in Astrophysical Journal ...
Analyzing data from NASA’s Hubble Space Telescope and several other observatories, astronomers have concluded that the bright red supergiant star Betelgeuse quite literally blew its top in 2019, losing a substantial part of its visible surface and producing a gigantic Surface Mass Ejection (SME). This is something never before seen in a normal star’s behavior. ...
A team of astronomers announced that they recently detected the farthest star ever seen. The star, nicknamed Earendel, is 28 billion light-years away from Earth. The discovery of a 13 billion-year-old star The star is cataloged as WHL0137-LS, but its catchier name, Earendel, is an Old English name meaning ‘morning star.’ The star spotted by the ...
Combining images taken with the Hubble Space Telescope over more than 20 years, a team of UA researchers has discovered that Eta Carinae, a very massive star system that has puzzled astronomers since it erupted in a supernova-like event in the mid-19th century, has a past that’s much more violent than they thought. The findings ...
The twin galaxies NGC 4496A and NGC 4496B dominate the frame in this image from the NASA/ESA Hubble Space Telescope. Both galaxies lie in the constellation Virgo, but despite appearing side-by-side in this image they are at vastly different distances from both Earth and one another. NGC 4496A is 47 million light-years from Earth while ...
This universe is truly vast and infinite, but could science prove that heaven really exists? Even if they already had the evidence and released it to the public, could people accept it? Did you know that despite spending most of their lives studying science, in their later years, many accomplished scientists became devoted to religion ...
The mass of dust and bright swirls of stars in this image is the distant galaxy merger IC 2431, which lies 681 million light-years from Earth in the constellation Cancer. The NASA/ESA Hubble Space Telescope has captured what appears to be a triple galaxy merger in progress, as well as a tumultuous mixture of star ...
The subject of this image from the Hubble telescope is a group of three galaxies, collectively known as NGC 7764A. They were imaged by the NASA/ESA Hubble Space Telescope, using both its Advanced Camera for Surveys and Wide Field Camera 3. The two galaxies in the upper right of the image appear to be interacting with one another. ...
The lazily winding spiral arms of the spectacular NGC 976 galaxy fill the frame of this image from the NASA/ESA Hubble Space Telescope. This spiral galaxy lies around 150 million light-years from the Milky Way in the constellation Aries. Supernova explosion in the NGC 976 galaxy Despite its tranquil appearance, the NGC 976 galaxy has played ...
