Thunderstorms are a powerful force of nature, but the ones we experience on Earth are dwarfed by the ones on the gas giant planet Saturn. They are huge and can be larger […]

'Old Earths': The Search for Ancient and Habitable (But Dying) Exoplanets

Researchers at Cornell University are taking a new approach to the search for alien life: looking for habitable planets older than Earth, […]

Astronomers Detect Complex Organics Around Nearby Young Star; Produce Them in Simulated Conditions in the Lab

Artist’s impression of the protoplanetary disk surrounding the young star MWC 480. Astronomers using the Atacama Large Millimeter/submillimeter Array, or ALMA, have detected the complex organic molecule methyl cyanide in the outer reaches of the star’s protoplanetary disk, where comets are believed to form. This discovery suggests that complex organic chemistry and potentially the […]

Hubble and Chandra Unveil Mysteries Concerning Dark Matter

From HubbleSite: “This collage shows images of six different galaxy clusters taken with NASA’s Hubble Space Telescope and Chandra X-ray Observatory. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide. Seventy-two large cluster collisions were studied in total. Using visible-light images from Hubble, […]

The most sophisticated and ambitious space-based observatory ever conceived by the human mind continues to take shape through various aerospace centers across the country, where work is progressing steadily with development of NASA’s James Webb Space Telescope (JWST). This year is a […]

Scientists Create Color-Based Catalog of Earthly Life Forms to Help Search for Alien Biology

A hypothetical rendering of colorful plant life on a habitable exoplanet. Although most such alien life, if it exists, found with this technique may be microscopic, it illustrates how analysis of color could help scientists learn more about the physical nature of alien biology.

While exoplanets are now being discovered by the thousands, it is still a painstaking process to determine any specific details about them, since they are so incredibly far away. However, astronomers have been devising new techniques to do just that, including […]

Chandra X-Ray Observatory Continues to Unfold Secrets of Universe

From NASA: “A newly discovered object in the galaxy NGC 2276 may prove to be an important black hole that helps fill in the evolutionary story of these exotic objects. This source , known as NGC2276-3c, is likely an intermediate-mass black hole with about 50,000 times the mass of the Sun. The main graphic […]
