Earth has been photographed multiple times from Mars, both from orbit (by orbital missions) and from the surface (rover missions).

NASA's newest planetary probe, the OSIRIS-REx asteroid sampling spacecraft, is merrily snapping its 'First-Light' images following the successful power up and health check of all of the probes science instruments, barely three weeks after a stunning sunset launch from the Florida Space Coast - as it is outbound to asteroid Bennu.

This year's Nobel Prize in physics is expected to be be conferred on the three scientists who invented the process that led to the discovery of gravitational waves, but not the scientist who made it possible.

When it comes to space helmets, there's one rule: you keep your helmet on. But there might be a couple of places in the Solar System where you can take your helmet off, just for a few moments, and not die instantly.

Images taken by the MESSENGER spacecraft have shown features on Mercury's surface that indicate that the planet is still tectonically active

Absolute Zero is the coldest possible temperature, the point at which you can no longer extract any energy from a system. How close have we gotten to this lowest of lows?

A total eclipses is an amazing sight, occurring whenever the Moon passes between the Sun and the Earth (or the Earth between the Sun and Moon) and totally obscures the incoming light.

Today, NASA announced that images taken by the Hubble Space Telescope have shown more evidence of water plumes on Europa's surface, bolstering evidence of a warm water ocean in its interior and providing opportunities for future study.

The month of October is upon us this weekend, and with it, one of the better meteor showers is active: the Orionids.

The northern lights are an amazing thing to behold, and can be seen regularly from locations spanning from Siberia and Alaska to Northern Canada and Scandinavia.
