This is an artist's impression of the interstellar comet 2I/Borisov as it travels through our solar system.

4.3 out of 5 stars 5,596. It is completely unique and contains a wealth of young stars. The exo-asteroid was likely pulled into our solar system from another star system 4.5 billion years ago. "What we found was quite puzzling; despite forming stars at a high rate, and therefore being the site of highly energetic processes, SPT0418-47 is the most well-ordered galaxy disc ever observed in the early Universe," said Simona Vegetti, study coauthor and Max Planck Research Group Leader at the Max Planck Institute for Astrophysics, in a statement. NASA's Spitzer Space Telescope captured the Tarantula Nebula in two wavelengths of infrared light. This photo of Saturn's large icy moon, Tethys, was taken by NASA's Cassini spacecraft, which sent back some

In these images by the ALMA telescopes, red and green highlight molecular gas while blue shows ionized hydrogen gas. The Eta Carinae star system, located 7,500 light-years from Earth, experienced a great explosion in 1838 and the Hubble Space Telescope is still capturing the aftermath.

The Hubble Space Telescope found a dwarf galaxy hiding behind a big star cluster that's in our cosmic neighborhood. Glowing gas clouds and newborn stars make up the Seagull Nebula in one of the Milky Way galaxy's spiral arms. This is an artist's illustration of gas and dust disk around the star HD 163296. The image above was taken by the Galileo spacecraft on November 25, 1999.
Composite image of B14-65666 showing the distributions of dust (red), oxygen (green), and carbon (blue), observed by ALMA and stars (white) observed by the Hubble Space Telescope.

Dust around the star, depicted here in an artist's illustration, may be the most likely cause of its strange behavior. An artist's impression of what a black hole might look like. The new results indicate that Terzan 5 is one of the bulge's primordial building blocks, most likely the relic of the very early days of the Milky Way. The Juice probe shown in this artist's impression aims to find out. The radio bubbles discovered by MeerKAT extend vertically above and below the plane of the galaxy. One of the brightest planetary nebulae on the sky and first discovered in 1878, nebula NGC 7027 can be seen toward the constellation of the Swan.
This An image of the Wild Duck Cluster, where every star is roughly 250 million years old. The Andromeda galaxy cannibalized and shredded the once-large galaxy M32p, leaving behind this compact galaxy remnant known as M32. This graphic shows various groupings of the moons and their orbits, with the newly discovered ones shown in bold. This is an artist's concept of the phenomenon. Scientists believe some craters on the dwarf planet are bright because they are relatively new. This mosaic image of asteroid Bennu is composed of 12 PolyCam images collected on December 2 by the OSIRIS-REx spacecraft from a range of 15 miles. $22.02. Further evidence of a supermassive black hole at the center of the Milky Way galaxy has been found. Astronomers have detected the most massive neutron star to date due to this delay.

This is a two-color composite image of comet 2I/Borisov captured by the Gemini North telescope on September 10. Trending at $16.98.



Comet 46P/Wirtanen will pass within 7 million miles of Earth on December 16.
