Little red dots (LRDs) are a class of small, red-tinted galaxies discovered by the James Webb Space Telescope. [1] [2] [3] Their discovery was published in March 2024, and they are currently poorly understood. [4] They appear to have existed between 0.6 and 1.6 billion years after the Big Bang, from 13.2 to 12.2 billion years ago. [1] LRDs were ...
UDFy-38135539 is within the annotated red circle Location of UDFy-38135539 (HUDF.YD3) UDFy-38135539 (also known as "HUDF.YD3") is the Hubble Ultra Deep Field (UDF) identifier for a galaxy which was calculated as of October 2010 to have a light travel time of 13.1 billion years [2] with a present proper distance of around 30 billion light-years.
BICEP (Background Imaging of Cosmic Extragalactic Polarization) and the Keck Array are a series of cosmic microwave background (CMB) experiments. They aim to measure the polarization of the CMB; in particular, measuring the B -mode of the CMB.
The Laniakea Supercluster (/ ˌ l ɑː n i. ə ˈ k eɪ. ə /; Hawaiian for "open skies" or "immense heaven") [2] or the Local Supercluster (LSC or LS) is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies.
The South Pole Telescope (SPT) is a 10-metre (390 in) diameter telescope located at the Amundsen–Scott South Pole Station, Antarctica.The telescope is designed for observations in the microwave, millimeter-wave, and submillimeter-wave regions of the electromagnetic spectrum, with the particular design goal of measuring the faint, diffuse emission from the cosmic microwave background (CMB).

The Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo (神岡 宇宙 素粒子 研究 施設, Kamioka Uchū Soryūshi Kenkyū Shisetsu, Japanese pronunciation: [kamioka ɯtɕɯː soɾʲɯꜜːɕi keŋkʲɯː ɕiseꜜtsɯ]) is a neutrino and gravitational waves laboratory located underground in the Mozumi mine of the Kamioka Mining and Smelting Co. near the Kamioka ...
The Korsch-type telescope will measure the shapes of galaxies at varying distances from Earth and investigate the relationship between distance and redshift. Euclid is a medium-class ("M-class") mission and is part of the Cosmic Vision campaign of ESA's Science Programme. Euclid was chosen in October 2011 together with Solar Orbiter. [12]
A cosmic-ray observatory is a scientific installation built to detect high-energy-particles coming from space called cosmic rays. This typically includes photons (high-energy light), electrons, protons, and some heavier nuclei, as well as antimatter particles.
