A team of researchers led by the Instituto Galego de Física de Altas Enerxías (IGFAE) from the University of Santiago de Compostela (Spain) has measured for the first time the speed and direction of the recoil of a newborn black hole formed through the merger of two others. The result, published today in the journal […]
About 80% of the universe’s mass is thought to consist of dark matter. Yet, little is known about the composition and structure of the particles that make up dark matter, presenting physicists with some fundamental questions. To explore this elusive matter, researchers are attempting to capture photons, or light particles, which are produced when dark […]
Finding life beyond Earth would be a major scientific discovery with significant implications for all areas of science and human thought. Yet, only one direct search for extraterrestrial life has ever been conducted.

Since the early days of human space exploration, the endeavor has been haunted by a very good question: why spend so much on space when there are so many urgent problems here on Earth?

Within our Milky Way galaxy, in the direction of the constellation Vulpecula, a cosmic “lighthouse” named PSR B1937+21 spins at an astonishing rate of 642 revolutions per second. It emits electromagnetic pulses that rival the precision of atomic clocks.

Radio astronomy took another step forward recently, with the completion of Phase III of the Murchison Widefield Array (MWA) in Western Australia. We’ve reported before on how the MWA has investigated everything from SETI signals to the light from the earliest stars. With this upgrade, the MWA will continue to operate with much needed improvements […]
Space has a trash problem, with defunct satellites, rockets, and smaller broken bits orbiting Earth at high speeds. The amount of space junk is only increasing, raising the risk of collision with active satellites and spacecraft, according to Kazunori Takahashi, associate professor in the Graduate School of Engineering at Tohoku University in Japan. Takahashi may […]
Using ESA’s INTEGRAL spacecraft, astronomers have detected exceptionally bright X-ray flares from the Cygnus X-1 X-ray binary system. This is the first time that such strong flaring activity has been observed in this system although it has been monitored for decades. The new findings were detailed in a paper published August 28 on the pre-print […]
Did you know nearly 17,500 satellites have been launched since 1957? Or what about the fact that more than 10% of those launches weren’t registered internationally?

University of Bristol astrophysicists are helping shed new light on an Earth-sized exoplanet 40 light years away where liquid water in the form of a global ocean or icy expanse might exist on its surface. That would only be possible if an atmosphere is present—a big mystery that the scientists are attempting to unravel and […]
Stargazers enjoyed a “Blood Moon” Sunday night during a total lunar eclipse visible across Asia and swaths of Europe and Africa.

Scientists have discovered that Mars has an interior structure similar to Earth’s. Results from NASA’s InSight mission suggest that the red planet has a solid inner core surrounded by a liquid outer core, potentially resolving a longstanding mystery.

While it may appear as just another spiral galaxy among billions in the universe, this image from the NASA/ESA Hubble Space Telescope reveals a galaxy with plenty to study. The galaxy, NGC 7456, is located over 51 million light-years away in the constellation Grus (the Crane).

Since the first discovery of planets beyond the solar system in 1995, more than 6,000 exoplanets have been identified. Many of these planets have properties that differ significantly from the eight planets in our solar system. How are such diverse exoplanets formed and evolved, and which of them could potentially become Earth-like planets capable of […]
