It takes a lot of ingenuity - not to mention a massive quantity of sheer force - to get satellites into orbit. Now space engineers are applying comparable ingenuity to the challenge of getting their missions out of there...

In the late 19th century, astronomers developed the technique of capturing telescopic images of stars and galaxies on glass photographic plates. This allowed them to study the night sky in detail. Over 500,000 glass plat...

Beginning skywatchers often think that the best time to look at the moon is when it is full, but experienced observers know that the moon is at its best for observing when it is around its first-quarter phase.

The launch, which had been delayed because of Dnepr availability, is the latest sign that despite the year-long hostilities between Russia and Ukraine, cooperative efforts that generate hard currency, such as Denpr, are ...

Planetary Habitability Laboratory: Scientists from Puerto Rico get together to study habitable planets. One of the main goals of exoplanet science is the detection and characterization of Earth-like planets. So far, ther...

Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide. The results, published ...

Roscosmos' Mikhail Kornienko will spend a year aboard the International Space Station. He talks about his father, a Russian military helicopter pilot that was part of search and rescue teams for the country's first cosmo...

Black holes break theories. These sites of extremely large masses in extremely small spaces invoke both of the behemoths of modern physics—general relativity (which rules over large masses) and... --

A small cloud of rocket fuel glowed faintly in the night sky above the Atlantic Ocean on the night of March 12, following a launch from Cape Canaveral Air Force Station, Florida. Skywatcher Scott Gauer photographed the g...

The iron heart of Earth's moon has been measured more precisely than ever before. In a new study, scientists used X-rays to study the type of iron likely presence in our lunar companion's core.

When galaxy clusters collide, their dark matters pass through each other, with very little interaction. Deepening the mystery, a study by scientists at EPFL and the University of Edinburgh challenges the idea that dark m...

Researchers from Brown University have completed a new analysis of an ancient Martian lake system in Jezero Crater, near the planet's equator. The study finds that the onslaught of water that filled the crater was one of...

A supermassive black hole with a mass four million times that of the Sun lies at the heart of the Milky Way galaxy....

Using observations from NASA's Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previ...

Millions of images of celestial objects, including asteroids, observed by NASA's Near-Earth Object Wide-field Survey Explorer (NEOWISE) spacecraft now are available online to the public. The data was collected following ...

The United States, Russia and Japan conducted separate, successful satellite launches March 25 during an unplanned seven-hour triple header. The post Delta 4, Dnepr and H-2A Complete a Launch Triple Header appeared first...
