Do you recognize the constellation of Orion? It may be harder than usual in this image because the camera has zoomed in on the center, and the exposure is long enough to enhance nebulas beyond what the unaided human eye can see https://t.co/YFlvBiy9DT
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
Sharp telescopic views of NGC 3628 show a puffy galactic disk divided by dark dust lanes. Of course, this deep portrait of the magnificent, edge-on spiral galaxy puts some astronomers in mind of its popular moniker, the Hamburger Galaxy https://t.co/w0jYwepV7u
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
To some, it looks like a giant chicken running across the sky. To others, it looks like a gaseous nebula where star formation takes place. Cataloged as IC 2944, the Running Chicken Nebula spans about 100 light years and lies about 6,000 light years away https://t.co/rCamwLU7Xs
It was just another day on aerosol Earth. For August 23, 2018, the identification and distribution of aerosols in the Earth's atmosphere is shown in this dramatic, planet-wide digital visualization https://t.co/dhDBdh3szj
The center of the Milky Way glows in every type of light. In the featured image, high-energy X-ray emission captured by Chandra X-Ray Observatory appears in green and blue, while low-energy radio emission captured by MeerKAT telescope array is colored red https://t.co/nsWlrjKxUo
The face-on spiral galaxy M77 lies a mere 47 million light-years away toward the constellation of the Sea Monster (Cetus). At that estimated distance, this gorgeous island universe is about 100 thousand light-years across https://t.co/axPKqLvYSn
Short star trails appear in this single 84 second long exposure, taken on March 6 from a rotating planet. The scene also captures the flight of a Falcon 9 rocket and Dragon cargo spacecraft over Cape Canaveral Air Force Station shortly after launch https://t.co/eBj8qorZJR
