Today was a big day for physicists and space science, with the announcement of the first confirmed detection of gravitational waves, 100 years after they had been predicted by Albert Einstein as a major aspect of his […]

New Study Suggests Earth May Be Surrounded by Long Hair-Like Filaments of Dark Matter

A new theoretical study has shown that Earth may be surrounded by long and very dense hair-like filaments of dark matter, which could potentially be directly observed by dedicated space-based dark matter detectors. Image Credit: NASA/JPL-Caltech

When hunting for dark matter, where would the best place to search for it be? The answer […]

The Coming of the Cosmic Old Age: New Survey Finds the Universe's Energy Output Is Decreasing With Time

A composite image of a galaxy as seen in different wavelengths by the GAMA survey. The results of the survey, which studied more than 200,000 galaxies in the local Universe, revealed that the latter’s total energy output has decreased by at least 50 percent during the last 2 billion years.

Type Ia supernova explosions can be considered as some of the Universe’s most spectacular and inviting attractions, signifying the death of very massive stars. With peak […]

To the Edge of Time: Celebrating 25 Years of Hubble Science (Part 4)

The breathtaking image of the Hubble eXtreme Deep Field, which was created from data that had been collected with the Hubble Space Telescope in 2003 and 2004. In order for the image to be created, the space telescope pointed towards a small patch of the sky for a total of 50 days, while […]

New Study Finds Unusual Mathematical Pattern in Cosmic Radio Bursts

A dramatic night-time image of the 64-m Parkes radio telescope in Australia, under the splenor of the Milky Way. The iconic telescope has detected during the last decade a total of 10 mysterious cosmic radio flashes, known as ‘fast radio bursts’. A new study now suggests that these astrophysical sources exhibit a surprising […]

New Studies Give More Boost to Search for Dark Matter in Milky Way

A view of the Milky Way galaxy in visible wavelengths. Two recent studies have provided more evidence which indicate that our galaxy is dominated in dark matter. In the image, the blue and red dots pinpoint the rotation curve tracers that were used in one of the studies and were colour-coded according to […]

Astronomers Measure Galactic Winds at Milky Way's Center, Detect Record-Breaking X-Ray Flares From Its Supermassive Black Hole

A composite image of the area around the supermassive black hole at the center of the Milky Way, known as Sagittarius A* (Sgr A*), taken with NASA’s Chandra X-ray space telescope. The colors in the main image represent medium, and high-energy X-rays as red, green, and blue respectively. The inset box shows a […]

Chandra X-Ray Observatory Helps Astronomers Weigh Most Massive Galaxy Cluster Discovered to Date

A composite, multi-wavelength image of the young galaxy cluster XDCP J0044.0-2033, also known as the Gioiello Cluster, which is located 9.6 billion light-years away. In the image, X-ray wavelengths appear purple, infrared appear as large red halos around some galaxies, and visible light appears as are red, green, and blue. Image Credit: X-ray: […]
