Three Centaurs Follow Uranus Through the Solar System
Astrophysicists from the Complutense University of Madrid have confirmed that Crantor, a large asteroid with a diameter of 70 km has an orbit similar to that of Uranus and takes the same amount of time to orbit the Sun. Researchers have demonstrated for the first time that this and a further two objects of the group of the Centaurs are co-orbital with Uranus.
Uruguayan astronomer Tabaré Gallardo suggested in 2006 that the asteroids Crantor and 2000 SN331 complete their orbits of the Sun in the same time period as Uranus - an orbit of approximately 84 Earth years. Now two researchers at the Complutense University of Madrid (UCM, Spain) have confirmed that in the case of Crantor this is true.

Researchers create housecat-inspired robot: By now, you’ve all seen the amazing robotic cheetah from Boston Dynamics that was able to smash Usain Bolt’s speed record. Well, it looks like that big cheetah bot now has a little brother called the “cheetah-cub robot” that is more closely modeled after a house cat.

The Turbulent, High-Energy Sky Is Keeping NuSTAR Busy
NuSTAR Status Update
NuSTAR has been busy studying the most energetic phenomena in the universe. Recently, a few high-energy events have sprung up, akin to “things that go bump in the night.” When one telescope catches a sudden outpouring of high-energy light in the sky, NuSTAR and a host of other telescopes stop what they were doing and take a better look.
For example, in early April, the blazar Markarian 421 had an episode of extreme activity, brightening by more than 50 times its typical level. Blazars are a special class of galaxies with accreting, or “feeding,” supermassive black holes at their centers. As the black holes feed, they light up, often ejecting jets of material. When the jets are pointing toward Earth, they are called blazars. By using telescopes sensitive to a range of energies to study how blazars vary, astrophysicists gain insight into black hole feeding processes and the physical conditions near the black hole.
