An international team of scientists, led by University of Missouri's Haojing Yan, used NASA's James Webb Space Telescope (JWST) to discover 14 new transient objects during their time-lapse study of galaxy cluster MACS0416 -- located about 4.3 billion li

In a study published in Nature Astronomy, astronomers from New Jersey Institute of Technology's Center for Solar-Terrestrial Research (NJIT-CSTR) have detailed radio observations of an extraordinary aurora-like display -- occurring 40,000 km abo

Absolutely empty -- that is how most of us envision the vacuum. Yet, in reality, it is filled with an energetic flickering: the quantum fluctuations. Experts are currently preparing a laser experiment intended to verify these vacuum fluctuations in a nove

The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them.

A Lancaster University PhD student has measured the optical depth of Saturn's rings using a new method based on how much sunlight reached the Cassini spacecraft while it was in the shadow of the rings.

Data from a NASA mission to map dark matter around galaxy clusters has been saved by a new recovery system designed by scientists at the University of Sydney. The system allowed the retrieval of gigabytes of information, even after communication failed an

The observed variations in chromium (Cr) isotope ratios in the Ryugu asteroid samples collected by Hayabusa2 likely resulted from elemental redistribution of slightly soluble Cr by water within the parent body, reveals a multinational study led by researc

ALMA (Atacama Large Millimeter/submillimeter Array) has demonstrated the highest resolution yet with observations of an old star. The observations show that the star is surrounded by a ring-like structure of gas and that gas from the star is escaping to t

Given the hostile conditions of extraterrestrial environments, unmanned rovers play a critical role in the exploration of planets and moons. NASA's Mars and lunar exploration rovers have significantly contributed to our understanding of these extraterres

Using the James Webb Space Telescope, an international team, including astronomer Alexander de la Vega of the University of California, Riverside, has discovered the most distant barred spiral galaxy similar to the Milky Way that has been observed to date

In the 1980s, geophysicists made a startling discovery: two continent-sized blobs of unusual material were found deep near the center of the Earth, one beneath the African continent and one beneath the Pacific Ocean. Each blob is twice the size of the Moo

The second- and fourth-most distant galaxies ever observed have been discovered in a region of space known as Pandora's Cluster, or Abell 2744, using data from NASA's James Webb Space Telescope (JWST). Following up on a deep field image of the area, an
