Webb captures luminous, face-on spiral galaxy NGC 7469

NGC 7469 is a luminous and face-on spiral galaxy. It is approximately 90,000 light-years in diameter and it lies approximately 220 million light-years from...

NASA Mars lander InSight falls silent after four years

It can be the end of the red dusty line for NASA's InSight lander. Because it has been silent on Mars for four years. The...

Astronomers may have uncovered how galaxies change their shape

Researchers may have answered a decades-old question about galaxy evolution. They have used the power of artificial intelligence (AI) to accomplish this. The Hubble Sequence...

Single-pulse behavior of rotating radio transient PSR J0628+0909 explored with FAST

Chinese astronomers have examined the single-pulse behaviour of a rotating radio transient (RRAT). It is also known as PSR J0628+0909. They have used the...

Cosmological enigma of Milky Way’s satellite galaxies solved

Astronomers say they have solved an outstanding problem that challenged our understanding of how the universe evolved. They have observed the spatial distribution of...

VLA and ALMA study Jupiter and Io

Karl G. Jansky Very Large Array (VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA) of the National Science Foundation frequently reveal important new facts...

New study confirms light from outside our galaxy brighter than expected

New measurements show that light emitted by stars outside our galaxy is two to three times brighter than light emitted by known populations of...

Hubble captures majestic barred spiral galaxy NGC 6956

The blue swirls of spiral galaxy NGC 6956 shine brightly against an inky black background. NGC 6956 is a barred spiral galaxy. It is...

Team of physicists suggests LIGO could be used to detect giant alien spacecraft

A group of physicists from various universities in the United States have collaborated on a new paper. The paper discussed the possibility of using...

Astronomers discover two potentially habitable exo-Earths around a star near the sun

An international scientific team led by researchers from the Instituto de Astrofisica de Canarias (IAC) discovered two planets. These planets have Earth-like masses in...

‘Peekabo’ dwarf galaxy is extremely metal-poor, study finds

Scientists have used the Southern African Large Telescope (SALT) and the Hubble Space Telescope (HST) and observed the dwarf galaxy HIPASS J1131-31. The galaxy...

The voids closest to us may not be entirely empty

The vast empty regions known as cosmic voids dominate the universe's large-scale structure. In the distribution of galaxies, these voids appear as holes hundreds...

Observations explore the properties of X-ray binary LMC X–4

Indian astronomers have used the AstroSat spacecraft to investigate LMC X-4. It is a high-mass X-ray binary system. The study's findings were published on...

Hubble captures dual views of an unusual star cluster

These two images may appear to be diametrically opposed. But they are actually images of the same cosmic object NGC 1850. Both images were...

Trading spaces: How swapping stars create hot Jupiters

Why do star clusters have hotter Jupiters than average? A group of astronomers has proposed a new solution. This solution involves a lot of...
