James Webb Telescope Spotted Two Unusually Bright Galaxies from the Early Universe

James Webb Telescope Spotted Two Unusually Bright Galaxies from the Early Universe

The galaxies are extremely bright, and one of the reasons for this may be that they could have been very massive, with lots of low-mass stars. Or they could be much less massive, consisting of a smaller number of extremely bright Population III stars.

Astronomers Discover Closest Known Black Hole to Earth

A team of astronomers has discovered the closest known black hole to Earth using data from the Gaia spacecraft. They did it by observing the Sun-like star moving in unexpected ways caused by the gravity of an unseen massive object.

James Webb Telescope Captures a Stunning View of Cartwheel Galaxy

Cartwheel is located at a distance of about 500 million light-years from Earth in the Sculptor constellation, and its estimated diameter is 150 thousand light-years.

Astronomers Discover the Oldest Galaxy in the Universe

Astronomers Discover the Oldest Galaxy in the Universe

The James Webb Space Telescope has detected the oldest galaxy in the universe – GLASS-z13. It is assumed that it was formed 300 million years after the Big Bang and is now 13.5 billion years old.

NASA's Chandra Observatory Spots Galaxy Clusters' Collision

NASA's Chandra Observatory Spots Galaxy Clusters' Collision

Abell 2146 is a pair of colliding galaxy clusters located nearly 2.8 billion light-years from our planet. Galaxy clusters contain hundreds of galaxies along with huge amounts of dark matter and hot gas.

The targets you will need to capture include orange and pink spirals or galaxies, blue ringed exoplanets, black holes, dark matter, white starburst supernovae, green rogue exoplanets, etc.

Hubble Space Telescope Captures Two Spiral Galaxies

Hubble Space Telescope Captures Two Spiral Galaxies

NASA unveiled a new image taken by the Hubble Space Telescope that shows two bright star-forming galaxies. The two galaxies are known as Arp 303. However, each galaxy has its individual name – IC 563 and IC 564.

Astronomers Discover a New Ultra-Faint Dwarf Galaxy

Astronomers Discover a New Ultra-Faint Dwarf Galaxy

Astronomers have discovered an ultra-faint galaxy called Toucana B. It is located 4.5 million light-years away, and scientists believe it could show us what stellar systems looked like at the beginning of the universe.

ESO Shares the First Image of the Black Hole at the Center of the Milky Way

ESO Shares the First Image of the Black Hole at the Center of the Milky Way

We cannot see the black hole itself, since it is completely black, but the luminous gas around proves that it is there: the dark central region is surrounded by a bright ring-like structure. The new image captures light distorted by the powerful gravity of the black hole.

Astronomers Discover an Ultra-Faint Satellite of Milky Way

Pegasus IV is classified as an ultra-faint galaxy. Such objects are characterized by extremely low brightness but are rich in mysterious dark matter. Ultra-faint galaxies are thought to be very ancient objects, formed shortly after the Big Bang.

LAMOST Discovered Over 1,500 Compact Galaxies

LAMOST Discovered Over 1,500 Compact Galaxies

Of the 1,417 new compact galaxies, 739 are Green Pea galaxies, 270 are Blueberry galaxies, and 388 are Purple Grape galaxies. These classes of stellar systems have received such strange names relatively recently because of their appearance.
