Talk about a heavy snack. For the first time, astronomers have witnessed a black hole swallowing a neutron star, the most dense object in the universe — all in a split-second gulp.
Feeling like you are being watched? It could be from a lot farther away than you think. Astronomers took a technique used to look for life on other planets and flipped it around — so instead of looking to see what’s out there, they tried to see what places could see us.

Look to the night sky this week for fascinating celestial show: the solar system’s three inner planets — Mercury, Venus and Mars — will all be visible. Use the crescent moon as a guide to find them in the sky.
During the fall and spring equinoxes, the sun rises due east and sets due west, creating an effect dubbed Chicagohenge (in reference to Stonehenge), when sunset is strikingly framed by the city’s east-west streets.
NASA on Monday released the first high-quality video of a spacecraft landing on Mars, a three-minute trailer showing the enormous orange and white parachute hurtling open and the red dust kicking up as rocket engines lowered the rover to the surface.
NASA’s Perseverance rover greeted its global audience on Twitter, beaming back to Earth the first image captured after touching down Thursday afternoon on Mars.
NASA prepares to land a rover on Mars designed specifically to detect signs of ancient life. Local astronomer and space exploration enthusiast Mark Hammergren tells us more about the mission.
A spacecraft designed by an Illinois researcher and professor will orbit Earth’s outermost atmospheric layer to better understand powerful bursts of radiation from the sun, also known as solar flares. Lara Waldrop tells us more.
Jupiter is preparing to pass Saturn, an event known as a great conjunction. On Dec. 21, the two planets will come closer to each other than they’ve been in nearly 400 years — and it will be visible to the naked eye.
Thursday’s full moon is the harvest moon, coming closest to the autumnal equinox. It will have some celestial company on Friday in the form of Mars, when the two will rise together and stay paired throughout the evening, according to experts.
