May 30, 2023 —With the help of citizen scientists, astronomers discovered what may be the last three planets that the Kepler Space Telescope saw before it was ...
May 25, 2023 —Astronomers are suggesting a new way to expand the search for habitable planets that takes into account a zone not previously considered: the space between the star and what's called soot-line ...
May 25, 2023 —A study presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth. ...
May 23, 2023 —Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the ...
May 23, 2023 —Scientists working in the lab have produced a signature nuclear reaction that occurs on the surface of a neutron star gobbling mass from a companion star. Their achievement improves understanding of ...
202年5月17日3 —Astronomers reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf ...
May 11, 2023 —Globular clusters are the most massive and oldest star clusters in the Universe. They can contain up to 1 million of them. The chemical composition of these stars, born at the same time, shows ...
May 11, 2023 —Astronomers have created a vast infrared atlas of five nearby stellar nurseries by piecing together more than one million images. These large mosaics reveal young stars in the making, embedded in ...
May 11, 2023 —Scientists analyzed over a decade's worth of data about 16 young supermassive stars orbiting the supermassive black hole at the center of the Milky Way galaxy. Supermassive stars typically are ...
May 8, 2023 —Astronomers have revealed new evidence about the properties of the giant bubbles of high-energy gas that extend far above and below the Milky Way galaxy's ...
May 4, 2023 —A 'beautiful effect' predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar -- a neutron star featuring a powerful ...
May 4, 2023 —The young star TW Hydrae is playing 'shadow puppets' with scientists observing it with NASA's Hubble Space Telescope. In 2017, astronomers reported discovering a shadow sweeping across ...
May 3, 2023 —Scientists have observed a star swallowing a planet for the first time. Earth will meet a similar fate in 5 billion ...
May 1, 2023 —Astronomers used NASA's James Webb Space Telescope to study a rocky exoplanet known as GJ 486 b. It is too close to its star to be within the habitable zone, with a surface temperature of about ...
2023年4月28日—Astronomers have discovered a new 'tidal disruption event,' in which the center of a galaxy lights up as its supermassive black hole rips apart a passing star. The outburst is the closest ...
Apr. 27, 2023 —A team of Japanese astronomers used simultaneous ground-based and space-based observations to capture a more complete picture of a superflare on a star. The observed flare started with a very ...
Apr. 27, 2023 —A new study looked at a known binary star (two stars orbiting around a mutual center of gravity), analyzing starlight obtained from a range of ground- and space-based telescopes. The researchers ...
Apr. 25, 2023 —In new 3D computer simulations, astrophysicists modeled black holes of varying masses and then hurled stars (about the size of our sun) past them to see what might happen. If they exist, ...
Apr. 18, 2023 —A star's chemical composition strongly influences the ultraviolet radiation it emits into space and thus the conditions for the emergence of life in its ...
Apr. 14, 2023 —An international team of astronomers announced the first exoplanet discovered through a combined approach of direct imaging and precision measurements of a star's motion on the sky. This new ...
