NGC 1333, a stellar nursery in Perseus. This large molecular cloud lies just 1000 light-years away, and spans 15 light-years. The reflection nebula contains hundreds of newly formed stars (less than a million years old) hidden within the dust cloud.

No, it's not a photo of a star taken on a hazy night. The Hubble Space Telescope captured this image of the elliptical galaxy M49 that contains ~200 billion stars that are roughly 6 billion years old. At the center is a supermassive black hole with ~500 million stellar masses. The galaxy lies ~56 million light-years away.

M15, a 13 billion year old globular cluster, sits just outside the Milky Way at a distance of 35,000 light-years. The cluster is ~200 light-years in diameter. It's one of ~170 globular clusters located around the halo of our galaxy. Globular clusters are dense structures often containing hundreds of thousands of stars.

If our Sun was located in a globular cluster, our night sky would look a bit like this:

A stunning view of M104, the famous Sombrero Galaxy. Located 28 million light-years away, it's approximately half the size of our Milky Way at 50,000 light-years wide.

Westerhout 40 (W40), the Butterfly Nebula, is located ~1400 light-years from Earth.
M11, the Wild Duck Cluster, is located ~6000 light-years from Earth. Astronomers believe the cluster is only 220 million years old. The open cluster contains ~2,900 stars, and is only 20 light-years across, making it one of the most dense open clusters known.

A wonderful image from Hubble of the central 40 light-years of the M2 globular cluster. M2 is one of the largest globular clusters that sit just outside the Milky Way. It is located ~55,000 light-years from Earth, and contains ~150,000 stars in a total diameter of ~175 light-years. The cluster is believed to be 13 billion years old.

On this day 60 years ago, NASA introduced the Mercury 7 astronauts. Front row, left to right: Walter M. Schirra, Jr., Donald K. Deke Slayton, John H. Glenn, Jr., and M. Scott Carpenter; back row, Alan B. Shepard, Jr., Virgil I. Gus Grissom, and L. Gordon Cooper, Jr.
The first-ever picture of a black hole. This supermassive back hole sits in the center of M87, a massive elliptical galaxy containing several trillion stars in the Virgo galaxy cluster 55 million light-years away. The mass of the back hole is 6.5 billion times that of our Sun. The bright ring is a disk of gas that orbits the black hole. As the gas orbits at very high speed, friction causes the gas to heat to extremely high temperatures.

Black hole anyone
ESO's telescopes (where I work) where used to generate a large percentage of the data which photographed the first black hole.

The two side boosters from SpaceX's Falcon Heavy rocket prepare to land back at Cape Canaveral Air Force Station on April 11, 2019, after successfully launching a 6000 kg Arabsat-6A communications satellite into orbit. The center booster of the three booster rocket successfully landed shortly after on a drone ship in the Atlantic.

This Hubble image is made from 7,500 photos taken over 16 years by the telescope. It contains ~265,000 galaxies, some over 13.3 billion light-years away, in an area smaller than the Moon's apparent size.

Love the thread! Can you give me a recommendation for a good free android star gazing app?
