For the first time, scientists have found the core of a dead planet orbiting a star 730 light-years from Earth.
Why it matters: Our solar system only has a few types of planets by comparison to the diversity of worlds out there orbiting other stars. Finding this bizarre world adds to that tapestry — and opens up new avenues for discovery.
Amazon Web Services announced last week it is forming a business division focused on helping government and commercial space entities become more agile and flexible by making use of the cloud.
The big picture: The new division — called the Aerospace and Satellite Solutions business segment — further solidifies Amazon's push into the space sector.
Teams of scientists are vying to be the first to spot a large, hypothetical planet that might be lurking in the outer reaches of our solar system.
Why it matters: Astronomers have found thousands of planets orbiting other stars, but the hunt for this possible planet orbiting our own Sun — called Planet X or Planet 9 by some — is showing just how little we know about our solar system.
