There are three known types of black holes: supermassive black holes that lurk in the hearts of galaxies, stellar mass black holes formed from stars that die as supernovae, and intermediate mass black holes with masses between the two extremes. It's generally thought that the intermediate ones form from the mergers of stellar mass black holes. If that is true, there should be a forbidden range between stellar and intermediate masses. A range where the mass is too large to have formed from a star but too small to be the sum of mergers. But a new study of data from LIGO suggests that there are black holes in that forbidden range.

How Warp Drives Actually (Might) Work
To make a warp drive you have to arrange spacetime so that you never locally travel faster than light but still arrive at your destination…faster than light. And in 1994 Mexican physicist Miguel Alcubierre figured out how.

Europe is Considering a Metal Asteroid Mission of its Own
The European Space Agency is considering a mission to a metal-rich asteroid. The target is Kleopatra, an M-type asteroid with two moons. These asteroids are relatively common, but they're difficult to observe because they're in the middle and outer regions of the main asteroid belt.

Blue Ghost Watches the Lunar Sunset, Signalling the End of its Mission
Firefly Aerospace's Blue Ghost 1 has completed its brief lunar mission. The lander spent two weeks conducting operations on the surface of the Moon before witnessing its final sunset as the Sun dipped below the horizon. This sunset marked the end of the mission, as Blue Ghost lacks the capability to maintain warmth during the freezing cold lunar night. Despite its short operational period, the lander accomplished its objectives, successfully testing all ten NASA payloads, gathering valuable data, and transmitting the findings back to Earth.

Good News. The Death Star Isn't Pointed Towards Us
It’s ok, Darth Vader hasn’t got our humble planet in his sights! No this Death Star is a binary system where both stars are locked into an orbit which will lead to their collision, unleashing a powerful gamma-ray burst when they do. The object, WR104 is otherwise known as the ‘Pinwheel Star’ due to the presence of a spiral of dust engulfing the system. Recent observations have accurately measured the orientation of the stars and thankfully they’re not pointed at the Earth. When they do eventually collide, it’ll be someone else’s problem.
