The Flame Nebula stands out in this optical image of the dusty, crowded star forming regions toward Orion's belt, a mere 1,400 light-years away. Click on the link and explore it by swiping the cursor https://t.co/FjvmwxXbeW

A ghostly visage on a cosmic scale, these remains of shocked, glowing gas haunt planet Earth's sky toward the constellation of Cygnus and form the Veil Nebula, a large supernova remnant, an expanding cloud born of the death explosion of a massive star https://t.co/PeemC9KRtx

The Great Nebula in Orion, an immense, nearby starbirth region, is probably the most famous of all astronomical nebulas. Here, glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1500 light-years away https://t.co/9lSo0HaKXh

The large emission nebula dubbed IC 1805 looks, in whole, like a human heart. The nebula glows brightly in red light emitted by its most prominent element: hydrogen https://t.co/YlWWQD1w0o

This stunning image of the star forming Orion Nebula was captured in 1901 by American astronomer and telescope designer George Ritchey. The original glass photographic plate has been digitized and light-to-dark inverted to produce a positive image https://t.co/3Upb7Ffnfv

This map, spanning over 600 million light years on a side, shows that our Milky Way Galaxy is on the edge of the Virgo Cluster of Galaxies, which is connected to the Great Attractor -- an even larger grouping of galaxies https://t.co/VOczGkqpfj

NASA's SOFIA -- an observatory flying in a modified 747 -- imaged the central region of the Milky Way with an instrument known as HAWC+ to visualize the magnetic field of our galaxy and this is the result https://t.co/p9TLtH1WJx

Star formation can be colorful. This chromatic cosmic portrait features glowing gas and dark dust near some recently formed stars of NGC 3572, a little-studied star cluster near the Carina Nebula https://t.co/5tlYelwZIK

This sunset captured by Heidelberg, Germany on April 15, 2019, contains a spot, Sun's active region AR2738 https://t.co/gCxQEtoJn5

Despite the cold, a chance to view the shimmering northern lights coaxed this skygazer onto the frozen surface of Lake Superior on the west coast of the Keweenaw Peninusla and offered this nocturnal crescendo as a reward https://t.co/tfWbNzfkcI
