Satellite fleet operator SES has selected Thales Alenia Space to build two C-band satellites, making the Franco-Italian manufacturer the first European company to win one of nine replacement satellite orders placed this year as a result of the U.S. Federal Communications Commission’s upcoming C-band spectrum auction.
Commercial satellite operatorSES has selected SpaceX and United Launch Alliance to each launch two geostationary satellites designed to replace C-band capacity in the United States that the Federal Communications Commission is repurposing for 5G cellular networks.
At first glance, it looks like something from an alien autopsy. A strange organ cut from a xenomorph’s thorax, under the flickering lights of an operating room in a top secret government facility, with venous tendrils dangling down to the floor, dripping viscous slime. (X-Com anyone?) But no, it’s just our Solar System. This strangely …

It's August and that means the Perseid meteors are inbound, starting this weekend this shower is a sure-fire bet, though 2020 sees the spectacle go down under somewhat challenging circumstances.

Twinkling stars might make for spectacular viewing on a hot summer’s night, but they are an absolute nightmare to astronomers. That twinkling is caused by disturbances in the Earth’s atmosphere, and can wreak havoc on brightness readings, a key tool for astronomers everywhere. Those readings are used for everything from understanding galaxy formation to the …

Astronomers have found another strange exoplanet in a distant solar system. This one’s an oddball because its size is intermediate between Earth and Neptune, yet it’s 50% more massive than Neptune. Astronomers have found what they call “puff planets” in other Solar Systems. Those are planets that are a few times more massive than Earth, …

Orbiters are giving us a chance to study the surface of Mars closely, and some of the features that pop to prominence are dry river channels. There are over 10,000 of them. But a new study suggests that glaciers on ancient Mars are responsible for many of them. According to the study, those glaciers and …

Since it launched in 2010, the Solar Dynamics Observatory has helped scientists understand how the Sun’s magnetic field is generated and structured, and what causes solar flares. One of the main goals of the mission was to be able to create forecasts for predicting activity on the Sun. Using mission data from the past …

Mars’ massive cloud is back. Every year during Mars’ summer solstice, a cloud of water ice forms on the leeward side of Arsia Mons, one of Mars’ largest extinct volcanoes. The cloud can grow to be up to 1800 km (1120 miles) long. It forms each morning, then disappears the same day, only to reappear …
