Astronomers have spotted four “strange” objects orbiting the massive black hole at the center of the Milky Way galaxy, according to a new study.
The rocky planets closest to the sun are made up of very different materials than the gas giants in the outer solar system. That’s because billions of years ago, our baby solar system was divided in two by a cosmic gatekeeper that prevented materials in the inner and outer regions from mixing.
Skywatchers are in for a treat Friday when the January full Moon, known as the wolf Moon, appears in the sky.
A gorgeous, incredibly detailed new image of the Milky Way’s center could help explain one of the enduring mysteries of our galaxy — why its heart is missing stars.
HONOLULU — Mysterious ultra-fast pinpricks of radio energy keep lighting up the night sky and nobody knows why. A newly discovered example of this transient phenomenon has been traced to its place of origin — a nearby spiral galaxy — but it’s only made things murkier for astronomers.
Here’s one express bus you’ll be glad you missed.

Near the start of the universe, approximately 12.5 billion years ago, supermassive black holes were fed gas “halos” that surrounded various galaxies, according to a new study.
From the first-ever image of a black hole to Navy UFO footage, the Apollo 11 anniversary and the latest attempts to land on the moon, 2019 has been a busy year in space.
A 427-foot asteroid shaped like a pyramid is set to whiz past Earth on Sunday.
Stars and comets make unlikely dance partners. Their gravitational partnership is one that astronomers have long suspected but have never seen — until now. For the first time, a Polish group has identified two nearby stars that seem to have plucked up their icy partners, swinging them into orbits around our sun.
NASA’s Hubble Space Telescope has spotted a pair of galaxies, collectively known as Arp 293, having come so close together that they share cosmic material.
Scientists have discovered a huge black hole that is challenging long-held assumptions about the cosmic bodies in the Milky Way.
Supermassive black holes at the hearts of galaxies may be blasting hot, turbulent waves of gas through the cosmos, keeping galaxy clusters alive with their heat.
Having been continuously observed since 1830, Jupiter’s Great Red Spot has fascinated researchers. But despite recent reports that the clouds involved are shrinking, the storm continues to be exceptionally strong, according to a new study.
NASA has spotted “battling galaxies” in deep space, courtesy of the Hubble Space Telescope.
Skywatchers in the eastern U.S. could enjoy a spectacular, but brief “unicorn meteor” shower on Thursday night.
An international research team led by NASA’s Goddard Space Flight Center in Maryland has, for the first time, detected water vapor above the surface of Jupiter’s moon Europa.
At nearly the beginning of time, the universe was shrouded in darkness. Then, early galaxies produced bright, hot stars that leaked brilliant light intergalactic space through small channels, turning the universe transparent.
There’s a hole in the story of how our universe came to be. First, the universe inflated rapidly, like a balloon. Then, everything went boom.
