Astronomers Found a Way to Predict When a Supernova Will Occur

Type II-P supernovae abruptly dump the matter surrounding them, which becomes a cloud. It gets very hot during the explosion and then gradually cools down, thus creating the effect of a slow-fading star.

Astronomers May Have Discovered Remnants of the Universe's Earliest Stars

At the end of their life cycle, first-generation stars would explode as exceptionally bright pair-instability supernovae, filling interstellar space with a characteristic mixture of heavy chemical elements.

Scientists Discover a Super-Earth Located Near Its Star's Habitable Zone

A super-Earth class exoplanet 4 times the mass of Earth was detected orbiting within the habitable zone of a red dwarf dubbed Ross 508. The star is located in the constellation Serpens and is five times smaller than our Sun.

Space

Astronomers Find Elusive Atoms in the Cosmic Web

The atoms are hard to spot because most of them are in the cosmic web in the form of gas so diffuse that there is no more than about one atom per cubic foot of space, which is much less than in any vacuum on Earth.

The Universe's Expansion Could Be Coming to an End

According to cosmologists, "soon" is within 100 million years. This means that humankind is on the verge of the beginning of the era of the Big Crunch. Physicists published their study in Proceedings of the National Academy of Sciences.

Telescope Captures an Image of a Dead Star's Shroud

EGB 6 will exist another few thousand years. After that, the stellar core will cool down and turn into a faint white dwarf, which will stop emitting enough ultraviolet light to ionize the ejected envelope.

Astronomers Discover an Ultra-Faint Satellite of Milky Way

Pegasus IV is classified as an ultra-faint galaxy. Such objects are characterized by extremely low brightness but are rich in mysterious dark matter. Ultra-faint galaxies are thought to be very ancient objects, formed shortly after the Big Bang.

LAMOST Discovered Over 1,500 Compact Galaxies

Of the 1,417 new compact galaxies, 739 are Green Pea galaxies, 270 are Blueberry galaxies, and 388 are Purple Grape galaxies. These classes of stellar systems have received such strange names relatively recently because of their appearance.

Astronomers Discover a New Type of Nebula

An international team of astronomers has discovered a new type of nebula around binary stars, a system of two gravitationally bound stars orbiting in closed orbits around a common center.

Space

Astronomers Discover the Most Distant Galaxy Ever Found

HD1 is 100 million light-years farther from Earth than the previous record-breaking galaxy GN-z11. According to preliminary calculations, HD1 produces about a hundred stars each year, which is ten times more than expected from a galaxy of this type.

The Universe Could Contain 40 Billion Billions of Black Holes

Scientists at the International School for Advanced Studies in Trieste (SISSA) have found that there are 40 billion billions (i.e., 4 followed by 19 zeros) stellar-mass black holes in the universe.

Space

Scientists Detect Up to 170 New Rogue Planets Wandering our Galaxy

If a planet is young and hot, its own residual heat helps find it. That's how scientists found the new rogue planets this time after analyzing 80,000 images taken over the past 20 years of astronomical observations.
