Some of the universe's stars have gone missing. But where did they go?

Space Mysteries: An international team of astronomers is on the hunt for objects that should be impossible.
Could the missing stars be a completely new phenomenon?

Stars don t just vanish or do they? For thousands of years, astronomers accepted the idea that the lights in the sky were fixed and unchanging. Even when it became clear that these lights were actually physical objects like the sun, one of the key assumptions for astrophysicists has been that they go through major changes very slowly, on timescales of millions or billions of years.
And when the most massive stars of all which are many times heavier than the sun do go through sudden and cataclysmic changes as they reach the ends of their lives, their passing is marked by the unmissable cosmic beacon of a ....

Take A Look At This 10 Trillion Pixel Image Of The Night Sky

Take A Look At This 10 Trillion Pixel Image Of The Night Sky
A photograph of the northern sky that weighs in at a whopping petabyte has become a treasure trove of information for astronomers.
Space is an impossibly massive zone that countless stars and planets reside in, and if you want to capture even a fraction of the sky then you re going to have to approach that challenge with some equally gigantic ideas. Astronomers across the world gathered for a chance to capture a photo of the northern sky according to SyFy, pooling resources over six years to create a 10 trillion pixel image. ....

Bad Astronomy | The DESI 10-terapixel sky survey map has a billion galaxies in it.

trillion pixels, and makes up a
petabyte of data a thousand terabytes, or a million gigabytes.
Oh, it also has over
a billion galaxies in it. A. Billion.
Like I said: Vast.
It s the result of the DESI Legacy Imaging Surveys, maps of the sky made by the three observatories (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall zband Legacy Survey, in combination with the orbiting WISE infrared observatory). They mapped the northern sky in seven colors, covering a third of the entire sky 14,000 square degrees, or the equivalent area of 70,000 full Moons on the sky. ....

This New 10 Terapixel Image of the Night Sky Contains 1 Billion Galaxies

This New 10 Terapixel Image of the Night Sky Contains 1 Billion Galaxies
Feb 08, 2021
It’s the result of the DESI Legacy Imagining Surveys, maps of the sky made by the three observatories (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Survey, in combination with the orbiting WISE infrared observatory). They mapped the northern sky in seven colors, covering a third of the entire sky 14,000 square degrees, or the equivalent area of 70,000 full Moons on the sky.
The ultimate goal is to better understand dark energy, the mysterious substance that’s accelerating the expansion of the Universe, by looking at the distribution of galaxies throughout the Universe. They’ll do that by picking tens of millions of the billion galaxies in the data and getting follow-up observations with the Dark Energy Spectroscopic Instrument (DESI), which will take spectra of those galaxies and find their distances. ....
