A comet the size of a mountain will come to within 87,000 miles of Mars on Sunday. It’s the type of encounter that only happens once in a million years, so don’t miss the chance to learn more about it. Watch the video above.
Boeing and California-based SpaceX have landed NASA contracts worth a total of $6.8 billion to launch an astronaut into space, the agency has announced.
SpaceX is printing rocket parts, including the thrust chamber on the engines for its Dragon V2 spacecraft, which it hopes will one day deliver NASA astronauts to the International Space Station.
Unlike most spacecraft, which are powered by rocket engines and cost hundreds of millions of dollars, these tiny satellites are expected to cost a few million dollars each and use the sun’s energy to push them across a windless space.
NASA’s Interface Region Imaging Spectrograph (IRIS) has captured video of a coronal mass ejection — solar material shooting out of the sun — in unprecedented detail.
With IRIS, scientists are trying to get to the bottom of what is known as “the solar corona mystery” (a phrase that a cursory Google search suggests is not yet a band name, if you were wondering).
Sometime between 11 p.m. tonight and 1 a.m. Saturday morning, the Earth is expected to pass through a trail of dust shed by the comet 209P/LINEAR hundreds of years ago. That could — emphasis on could — mean the peak of a never-before-seen meteor shower, the May Camelopardalids. The astronomy website Slooh.com has partnered with NASA to provide this live feed from cameras in Alabama.
Here, science reporter Deborah Netburn explains what may happen when we pass through that debris field — and why we may see nothing at all.
It’s called Beta Pictoris b, and it spins at 62,000 miles per hour.
