April 24 marked the 30th anniversary of the Hubble Space Telescope (HST), which has given humanity some of the most […]

The Next Big Thing: NASA Officially Gives the Go-Ahead for WFIRST Telescope—An Interview With Dr. Neil Gehrels

An artist’s concept of the Wide Field Infrared Survey Telescope (WFIRST). NASA has officially chosen the infrared-space telescope as the scientific successor to the James Webb Space Telescope, with a projected launch date around the 2024 timeframe. WFIRST is expected to make significant contributions in the study of dark energy and the characterisation […]

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 […]

In Search of the Invisible Universe: Newly Discovered Dwarf Galaxies Around the Milky Way Might Hold Clues to Dark Matter

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 […]

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: […]
