To aid in the search for life on Mars, people should look at the way primitive life on Earth modifies the environment around it.

Let's take a deep hopeful breath and look forward, shall we? People have discovered that it's pretty difficult to move to Canada. So there's a lot of talk about going to Mars.

In 1900, astronomer Joseph Lunt made a discovery: Peering through a telescope at Cape Town Observatory, the British-South African scientist spotted this beautiful sight in the southern constellation of Grus (The Crane): ...

After the smooth arrival of ESA's latest Mars orbiter, mission controllers are now preparing it for the ultimate challenge: dipping into the Red Planet's atmosphere to reach its final orbit.

The first ExoMars mission arrived at the Red Planet in October and now the second mission has been confirmed to complete its construction for a 2020 launch.

The detection of hydrated salts within Mars' intriguing, seasonally appearing dark streaks aren't necessarily proof of liquid water, according to a new study.

Researchers from the University of Amsterdam's (UvA) GRAPPA Center of Excellence have just published the most precise analysis of the fluctuations in the gamma-ray background to date. By making use of more than six years...

With the discovery of gravitational waves, says Kip Thorne, Caltech's Richard P. Feynman Professor of Theoretical Physics, emeritus, "we humans are embarking on a marvelous new quest: the quest to explore the warped side...

An important part of studying celestial objects is understanding and removing the background noise.

The planet Mars has few things in common. Both planets have roughly the same amount of land surface area, sustained polar caps, and both have a similar tilt in their rotational axes, affording each of them strong seasona...

Astronomer J. Craig Wheeler of The University of Texas at Austin thinks that Betelgeuse, the bright red star marking the shoulder of Orion, the hunter, may have had a past that is more interesting than meets the eye. Wor...

Everyone has a backstory, even our own Milky Way galaxy. And much like social media, the picture is not always as pretty as it appears on the current surface, says Texas A&M University astronomer Casey Papovich.

The Pan-STARRS project, including astronomers at the Max Planck Institutes for Astronomy in Heidelberg and for Extraterrestrial Physics in Garching, is publicly releasing the world's largest digital sky survey today. The...

Although there are no seasons in space, this cosmic vista invokes thoughts of a frosty winter landscape. It is, in fact, a region called NGC 6357 where radiation from hot, young stars is energizing the cooler gas in the ...

We would normally associate jet streams with the weather but, thanks to ESA's magnetic field mission, scientists have discovered a jet stream deep below Earth's surface - and it's speeding up.

A colossal jet stream, a river of molten iron has been found surging under Alaska and Siberia which is estimated to be about 420 km wide (260 miles) some some 3,000 kilometers (1,864 miles) below the surface and nearly a...

The jet stream within the Earth's molten iron core has been discovered by scientists using the latest satellite data that helps create an 'x-ray' view of the planet. "The European Space Agency's Swarm satellites are prov...
