Astronomers Find a New Potential Habitable Exoplanet 31 Light-Years Away

Astronomers Find a New Potential Habitable Exoplanet 31 Light-Years Away

The planet, named Wolf 1069 b, is located in the habitable zone of its star, a red dwarf. A habitable zone is an area where conditions are suitable for the existence of liquid water on the surface, which means that the planet can hypothetically sustain life.

Astronomers Discover a "Mirror Image" of the Milky Way from Billions of Years Ago

Astronomers Discover a "Mirror Image" of the Milky Way from Billions of Years Ago

Using the James Webb Space Telescope, astronomers have discovered a galaxy that looks very similar to our Milky Way in its early stages of evolution. It was named the Sparkler because almost two dozen glittering globular clusters orbit it.

Astronomers Capture a Radio Signal from an Extremely Distant Galaxy

Astronomers Capture a Radio Signal from an Extremely Distant Galaxy

This discovery was made possible by a phenomenon called gravitational lensing, in which light emitted by a source is bent by the presence of another massive body, effectively amplifying the signal, the astronomers explain.

Scientists Discover Two Supermassive Black Holes in Merging Galaxies

Scientists Discover Two Supermassive Black Holes in Merging Galaxies

It will take several hundred million years for this particular pair of black holes to collide, but the insight gained from this observation could help scientists better estimate how many pairs of black holes in the universe are close to colliding.

Hubble Captured a Star-Studded Cosmic Cloud

NGC 6530 is a cluster of several thousand stars embedded within the Lagoon Nebula – a gigantic interstellar cloud of gas and dust. It is the nebula that gives this image its distinctive smoky appearance.

NASA Shared a 12-year Timelapse of the Entire Universe

NASA Shared a 12-year Timelapse of the Entire Universe

NEOWISE has added hundreds of brown dwarfs to its catalog, monitored 1,000 protostars, gas balls hot enough to ignite and become stars, and discovered millions of supermassive black holes at the centers of distant galaxies.

A Well-Known Ground Detector Can Detect Alien Spaceships

A Well-Known Ground Detector Can Detect Alien Spaceships

A team of American scientists has published a new study, which has not yet passed scientific peer review, in which they propose to use the world's largest detector for detecting gravitational waves LIGO to find alien spaceships.

Astronomers Created a New Interactive Map of the Universe

Astronomers Created a New Interactive Map of the Universe

The full map of the observable universe is actually a slice of cosmos with a thickness of about 10 degrees. However, it still gives an idea of the scale of our universe as well as its stars and galaxies up to 13.7 billion light-years away.

James Webb Telescope Spotted Two Unusually Bright Galaxies from the Early Universe

James Webb Telescope Spotted Two Unusually Bright Galaxies from the Early Universe

The galaxies are extremely bright, and one of the reasons for this may be that they could have been very massive, with lots of low-mass stars. Or they could be much less massive, consisting of a smaller number of extremely bright Population III stars.

Astronomers Discover Closest Known Black Hole to Earth

A team of astronomers has discovered the closest known black hole to Earth using data from the Gaia spacecraft. They did it by observing the Sun-like star moving in unexpected ways caused by the gravity of an unseen massive object.

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

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

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.

Astronomers Find Elusive Atoms in the Cosmic Web

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.

Astronomers Discover the Oldest Galaxy in the Universe

Astronomers Discover the Oldest Galaxy in the Universe

The James Webb Space Telescope has detected the oldest galaxy in the universe – GLASS-z13. It is assumed that it was formed 300 million years after the Big Bang and is now 13.5 billion years old.
