The Baby Boom Galaxy is a starburst galaxy located about 12.477 billion light years away (co-moving distance is 25.08 billion light years). [1] [4] Discovered by NASA's Spitzer Science Center at the California Institute of Technology, the galaxy is the record holder for the brightest starburst galaxy in the very distant universe, with brightness being a measure of its extreme star-formation ...
Widely recognised as being among the largest known stars, [21] radius decreased to ~500 R ☉ during the 2020 great dimming event. [75] R Horologii: 630 [60] L/T eff: A red giant star with one of the largest ranges in brightness known of stars in the night sky visible to the unaided eye. Despite its large radius, it is less massive than the Sun.
On 6 and 7 March 2011, VY CMa was observed at near-infrared wavelengths using interferometry at the Very Large Telescope. The size of the star was calculated using the Rosseland Radius, the location at which the optical depth is 2 ⁄ 3, [55] with two modern distances of 1.14 +0.11 −0.09 and 1.20 +0.13 −0.10 kpc.
The list specifically excludes both white dwarfs – former stars that are now seen to be "dead" but radiating residual heat – and black holes – fragmentary remains of exploded stars which have gravitationally collapsed, even though accretion disks surrounding those black holes might generate heat or light exterior to the star's remains ...
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).
For the first time ever, the Hubble Space Telescope spotted an individual main sequence star at 9 billion light-years away. That's just a couple billion years after the Big Bang.
The James Webb Space Telescope has captured new detailed portraits of 19 spiral galaxies filled with millions of stars and glowing gas and dust. ‘Mind-blowing’ new images reveal 19 galaxies ...
A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
