WHL0137-LS, also known as Earendel, is a star located in the constellation of Cetus.Discovered in 2022 by the Hubble Space Telescope, it is the earliest and most distant known star, at a comoving distance of 28 billion light-years (8.6 billion parsecs).
NASA recently spotted the vibrant colors that make up the "cosmic wreath," a swarm of stars and dust on the outskirts of the Small Magellanic Cloud, one of the closest galaxies to the Milky Way ...
In May 2020, a Nasa space telescope was observing the leftovers of an exploded star in a nearby galaxy. As it did, it captured a bright and extremely fast X-ray flash.
Artificial star will be visible to ground telescopes. The purpose of the so-named Landolt NASA Space Mission is to place a calibrated light source into orbit at a distance of 22,236 miles from the ...
Artist's conception of a white dwarf, right, accreting hydrogen from the Roche lobe of its larger companion star A nova (pl. novae or novas) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star (hence the name "nova", Latin for "new") that slowly fades over weeks or months.
Up until the discovery of JADES-GS-z13-0 in 2022 by the James Webb Space Telescope, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, [7] having a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).
James Webb Space Telescope unveils star-forming Leo P galaxy. The team studied Leo P using NASA’s James Webb Space Telescope, which imaged the dwarf galaxy with the instrument's Near-Infrared ...
In 2010, a new satellite of planet Jupiter was discovered with the 200-inch Hale, called S/2010 J 1 and later named Jupiter LI. [ 38 ] In October 2017 the Hale Telescope was able to record the spectrum of the first recognized interstellar object, 1I/2017 U1 ("ʻOumuamua"); while no specific mineral was identified it showed the visitor had a ...
