The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic redshift survey using a dedicated 2.5-m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States. The project began in 2000 and was named after the Alfred P. Sloan Foundation, which contributed significant funding.
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.
The Laniakea Supercluster (/ ˌ l ɑː n i. ə ˈ k eɪ. ə /; Hawaiian for "open skies" or "immense heaven") 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.
Astronomers have used the Gaia space telescope to spy some of the first building blocks of the Milky Way galaxy: two ancient streams of stars named Shakti and Shiva that helped our home galaxy ...
The Local Bubble, or Local Cavity, is a relative cavity in the interstellar medium (ISM) of the Orion Arm in the Milky Way.It contains the closest of celestial neighbours and among others, the Local Interstellar Cloud (which contains the Solar System), the neighbouring G-Cloud, the Ursa Major moving group (the closest stellar moving group) and the Hyades (the nearest open cluster).
There have been detailed maps of the Milky Way before, but none quite so ornate as this. Researchers in the HI4PI sky survey have created a fine-grained map of our home galaxy using its most ...
Hubble Space Telescope image of the region of the sky where the Great Attractor is located. The Great Attractor is a region of gravitational attraction in intergalactic space and the apparent central gravitational point of the Laniakea Supercluster of galaxies that includes the Milky Way galaxy, as well as about 100,000 other galaxies.
Like our home galaxy, the newly discovered ceers-2112 is a barred spiral galaxy, and it’s now the most distant of its kind ever observed. The bar at the center of the structure is made of stars ...
