While aiming for massive gas cloud, astronomers spot differences in thickness of Milky Way Galaxy

Space may appear vast and empty, but it's full of cosmological objects that are invisible to the human eye. From our vantage point on Earth, many of these objects fall between astronomers and what they hope to observe, impacting what they find. This scenario was recently encountered by...

NASA's planet hunter satellite observes smaller object in a black hole pair directly for the first time

Several international research groups have already confirmed the theory that there are two black holes at the center of the distant galaxy OJ 287, first suggested by astronomers at the University of Turku, Finland. A new study shows that satellite observations conducted in 2021 revealed the...

Astronomers discover an Earth-sized exoplanet orbiting a nearby ultracool dwarf star

An international team of astronomers reports the discovery of a new Earth-sized exoplanet that orbits an ultracool dwarf star located just 54.6 light years away. The newfound alien world, designated SPECULOOS-3 b, is slightly smaller but much hotter than our planet. The finding was reported in a...

Einstein Telescope could launch a new era in astronomy

It's still just a plan, but a new telescope could soon be measuring gravitational waves. Gravitational waves are something like the sound waves of the universe. They are created, for example, when black holes or neutron stars collide.

High-speed baby stars circle the supermassive black hole Sgr A* like a swarm of bees

Observational astronomy shows that newly discovered young stellar objects (YSOs) in the immediate vicinity of the supermassive black hole Sagittarius A* located in the center of our galaxy behave differently than expected. They describe similar orbits to already known young evolved stars and are...

Marsquakes could reveal whether liquid water exists underground on red planet

If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars—or marsquakes—could offer a new tool in the search, according to a team led by Penn State scientists.

Earth's rotating inner core is starting to slow down — and it could alter the length of our days

A new study confirms that Earth's inner core has been rotating more slowly than usual since 2010. This mysterious "backtracking" could also end up slightly altering the planet's overall rotation, lengthening our days.
