It’s oh-so-easy to be absolutely mesmerized by these spiral galaxies. Follow their clearly defined arms, which are brimming with stars, to their centers, where there may be old star clusters and – sometimes – active supermassive black holes.
Certainly, we could tap into all the heat and kinetic energy of a black hole's accretion disk and jets, but even if all you had was a black hole in empty space, you could still extract energy from a trick known as the Penrose process.
A small black hole is helping scientists understand how mysterious cosmic rays can barrel through the Universe and hit Earth at nearly the speed of light.
If life ever existed on Mars, the Perseverance rover’s verification of lake sediments at the base of the Jezero crater reinforces the hope that traces might be found in the crater.
Astronomers using NASA's Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere.
An international team of researchers has gained new insights into the formation of diamond rain on icy planets such as Neptune and Uranus, using the X-ray laser European XFEL in Schenefeld.
Virgin Galactic has grounded its current space tourism flight after a small part of its mothership unintentionally detached. Richard Branson's Virgin Galactic has been offering space tourism missions since August 2023.
A team of scientists has just discovered some oddly reflective dust-covered boulders in an area of the Moon already known for its peculiarities.
Using the TESS space telescope, astronomers detected an exoplanet with a perpetual lava hemisphere.
An international team of astronomers has detected for the first time H-alpha emission in individual galaxies during the so-called Epoch of Reionization, or cosmic dawn.
An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.
ESA's Mars Express has revisited one of Mars's most mysterious features to clarify its composition. Its findings suggest layers of water ice stretching several kilometers below ground—the most water ever found in this part of the planet.
New research shows the early lunar crust which makes up the surface of the Moon was considerably enriched in water more than 4 billion years ago, counter to previously held understanding.
Astronomers using the James Webb Space Telescope (JWST) have detected the earliest known black hole. Located more than 13 billion light-years away, it dates to a mere 400 million years after the Big Bang.
Beta Pictoris has been revealed by many telescopes, even Hubble, to be home to the most amazing disk. Over the years the second disc was revealed.
