Scientists have been looking for the reclusive neutron star expected to be at the center of supernova 1987A for over thirty years, and they may have finally found it in new images from the Chandra and NuSTAR observatories. Plus, a look at conflicting papers on the object that wiped out the dinosaurs, a roundup of news, and this week’s What’s Up.
A newly found object nearly four times farther out from the Sun than Pluto now holds the record for the farthest observed in our solar system. Plus, forming super-Earths, finding potentially habitable planets, jellyfish galaxies, the Crab Nebula, and this week’s What’s Up.
A new theory has been proposed that could answer the question of what causes recurring landslides on Mars: small-scale ice melting just below the surface may leave the regolith vulnerable to wind. Plus, a look at some of Earth’s ancient climate changes, a gamma-ray source, puffy galaxies, and this week’s What’s Up.
Dark matter is only acted upon by the force of gravity according to new research, which constrains the potential range of mass for the elusive particles. Plus, how precipitation affects the Earth’s crust, a pair of ancient asteroid impacts in Germany, NASA’s Day of Remembrance, and this week’s What’s Up.
We’re going to kick off the year with a look at upcoming night sky events, as well as scheduled spacecraft milestones and exciting space flights. Expect to hear about planets, eclipses, space tourism, crewed space missions, and a new ground-based telescope getting ready to go online. This year sounds potentially exciting in a bunch of good ways!
