ULAS J0015+01. ULAS J0015+01 is the designation given to a star discovered on July 10, 2014 as the farthest star in bound of the gravitational attraction of the Milky Way galaxy. It is estimated to lie at 900,000 light-years from the Earth, beyond the reaches of the Magellanic Clouds. [1] Another star, ULAS J0744+25, was a bit closer. [2]
The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
Ceers-2112 formed soon after the big bang created the universe (which is estimated to be 13.8 billion years old), and the galaxy’s distinct structure was already in place 2.1 billion years later.
Galactic year. The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. [1] One galactic year is approximately 225 million Earth years. [2] The Solar System is traveling at an average speed of 230 km/s (828,000 km/h) or 143 mi/s (514,000 mph) within its ...
ESO 383-76 ( ESO 383-G 076) is an elongated, X-ray luminous supergiant elliptical galaxy, residing as the dominant, brightest cluster galaxy (BCG) of the Abell 3571 galaxy cluster, the sixth-brightest in the sky at X-ray wavelengths. [3] It is located at the distance of 200.6 megaparsecs (654 million light-years) from Earth, and is possibly a ...
The Small Magellanic Cloud ( SMC) is a dwarf galaxy near the Milky Way. [5] Classified as a dwarf irregular galaxy, the SMC has a D 25 isophotal diameter of about 5.78 kiloparsecs (18,900 light-years), [1] [3] and contains several hundred million stars. [5] It has a total mass of approximately 7 billion solar masses. [6]
In 2022, study coauthor Hans-Walter Rix and his colleagues used Gaia to peer into the heart of the Milky Way and discovered the oldest stars ever found in the galaxy during their “galactic ...
The Large Magellanic Cloud ( LMC) is a dwarf galaxy and satellite galaxy of the Milky Way. [7] At a distance of around 50 kiloparsecs (163,000 light-years ), [2] [8] [9] [10] the LMC is the second- or third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal ( c. 16 kiloparsecs (52,000 light-years) away) and the possible ...
