NASA observatory falls out of orbit, burns in atmosphere after 22 years of studying the cosmos

The 3,200-pound Swift aircraft most likely burned up after re-entry, although NASA said some components may have survived. 

Swift's UVOT captured the new supernova (circled) in three exposures taken on Jan. 22, 2014. Mid-ultraviolet light is shown in blue, near-UV light in green, and visible light in red.

Introducing Janus, the exotic 'two-faced' white dwarf star

Scienets have observed a white dwarf star, named for the two-faced ancient Roman god, that appears to have two sides with completely different compositions.

 An artist's concept shows the two-faced white dwarf star nicknamed Janus.

The universe is reportedly 26.7 billion years old - study

Astrophysicists have tried to calculate how long the universe has existed by measuring time elapsed since the Big Bang and evaluating the oldest stars at high redshifts of light from other galaxies.

 A galaxy is seen distorted into an Einstein ring due to gravitational lensing warping space and time.

NASA rover reveals new evidence about organic molecules on Mars

The Perseverance landed at the Jezero crater in 2021, an area in the planet's northern hemisphere that once was flooded with water and home to an ancient lake basin.

NASA’s Curiosity Mars rover used its black-and-white navigation cameras to capture panoramas of “Marker Band Valley” at two times of day on April 8. Color was added to a combination of both panoramas for an artistic interpretation of the scene.

How to kill a star? Astronomers see a 'demolition derby' scenario

Researchers said the gamma-ray burst they observed may have been caused by the collision of two compact stars in the densely packed and chaotic environment.

The luminous, hot star Wolf-Rayet 124 (WR 124) is prominent at the center of the James Webb Space Telescope’s composite image combining near-infrared and mid-infrared wavelengths of light from Webb’s Near-Infrared Camera and Mid-Infrared Instrument.

Scientists find organic molecules in galaxy 12 billion light years away - study

The organic molecules found in this distant galaxy are not signs of life. Found via NASA's James Webb Space Telescope, their discovery raises questions about star formation.

 Astronomers using the Webb telescope discovered evidence of complex organic molecules similar to smoke or smog in the distant galaxy shown here.

Israeli astrophysicists may have solved the mystery of early massive galaxies

A new theoretical model made by Israeli astrophysicists reveals an excess of massive galaxies, in contrast to previously accepted theories.

Aliens may be looking for Earth but can't find us - study

Humanity has been looking for aliens for decades but has yet to find any evidence. A new study suggests we may just be in a sort of cosmic blind spot for alien radio signals.

The mystery of the runaway black hole - study

A mysterious trail of stars puzzled scientists for some time. While a theory posited this to be a supermassive black hole passing through a gas cloud, a simpler theory has now emerged.

 This is an artist's impression of a runaway supermassive black hole that was ejected from its host galaxy as a result of a tussle between it and two other black holes. As the black hole plows through intergalactic space it compresses gas and forms stars (Illustrative).

Scientists discover that galactic collisions cause quasars - study

Contrary to previous beliefs that the quasars are formed at the peak of galactic collision, researchers found that they are actually formed during the initial stages of collision.

 This artist’s impression shows how ULAS J1120+0641, a very distant quasar powered by a black hole with a mass two billion times that of the Sun, may have looked.

One of the oldest galaxies ever was found with James Webb Space Telescope

The observation is among the first of a distant galaxy using NASA's James Webb Space Telescope since it was launched in December 2021.

 This illustration depicts NASA’s James Webb Space Telescope – the largest, most powerful, and most complex space science telescope ever built – fully unfolded in space. The telescope’s first full-color images and spectroscopic data will demonstrate Webb at its full power, ready to begin its mission
