In previous studies, astrophysicists observed two black holes colliding with two neutron stars in separate events, but never merging. This event marks the first detection of a merger between a black hole and neutron star, in which one basically swallows the other. The collisions and resulting gravitational waves offer a rare glimpse into how cataclysmic cosmic explosions affect the expansion and shrinking of space-time.

Neutron stars are essentially the corpses of giant stars up to 30 times as massive as the sun, and black holes are condensed space regions where gravitational forces are so strong that not even light can escape. When these astronomical objects collide, they dance around each other until they finally meet, resulting in a massive explosion.
- Powerful refractor telescope: The Celestron AstroMaster 70AZ is a powerful and user-friendly refractor telescope with fully coated glass optics, a sturdy yet lightweight frame, 2 eyepieces, a red dot finder scope, and an adjustable-height tripod.
- High-quality 70mm optics: Our Celestron telescope features a powerful, fully coated 70mm glass optic objective lens. Erect image optics allow you to observe celestial objects at night and terrestrial targets like wildlife and landscapes during the day.
- Quick setup & lightweight frame: This telescope for adults features a lightweight frame and a panning handle with Alt-Az control for smooth and accurate pointing. Setup is quick and easy, with no tools required.
- Included accessories: We’ve included 2 eyepieces (20mm and 10mm), an erect image star diagonal, a travel tripod, and a red dot finder scope. Download our BONUS Starry Night Basic Edition astronomy software for interactive sky simulation.
We suspected that these systems existed, but they had eluded us until now. Continued observations of these binaries will reveal their formation channels and could one day help us understand how matter behaves at the extreme densities these processes probe,” said Ryan Magee, a postdoctoral scholar at Caltech who helped in analyzing the LIGO signals.
