Using the Very Large Telescope Interferometer (VLTI), an international team of astronomers has observed a young Herbig Ae-type star known as T Coronae Australis. As a result, they found that the star has a companion separated ...
In the realm of science fiction, Dyson spheres and ringworlds have been staples for decades. But it is well known that the simplest designs are unstable against gravitational forces and would thus be torn apart. Now a scientist ...
By analyzing the data from Leahy's atlas of double radio-sources and NASA/IPAC Extragalactic Database (NED), Serbian astronomers have explored an X-shaped radio galaxy designated 3C 315. Results of the new study, published ...
An international team of astronomers reports the detection of two new brown dwarfs orbiting distant stars using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound objects are about 30 times more massive than ...
The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away that has long been a key target for planet formation ...

Italian astronomers report the detection of a new X-ray binary (XRB), which has received the designation 4XMM J181330.1-17511 (J1813 for short). The newfound object represents the rare subclass of XRBs known as supergiant ...
Using the Australia Telescope Compact Array (ATCA), astronomers have performed high-resolution observations of a nearby pulsar wind nebula in the supernova remnant G11.2−0.3. Results of the observational campaign, published ...
A new study by Rice University researchers Sho Shibata and Andre Izidoro presents a compelling new model for the formation of super-Earths and mini-Neptunes—planets that are 1 to 4 times the size of Earth and among the ...
