Hubble captures the delicate edge of the enormous Cygnus Loop nebula

The latest image captured by the Hubble Space Telescope shows a glimpse of an elegant, delicate portion of a huge round nebula which was formed when a star 20 times the mass of our sun exploded between 10,000 and 20,000 years ago.

The supernova explosion was so fierce that the dust and gas at the edge of the shock wave is still moving at a speed of over 200 miles per second, and since the event the remnant has expanded out 60 light-years from its original position.

While appearing as a delicate and light veil draped across the sky, this image from the NASA/ESA Hubble Space Telescope actually depicts a small section of the Cygnus supernova blast wave, located around 2,400 light-years away. The name of the supernova remnant comes from its position in the northern constellation of Cygnus (The Swan), where it covers an area 36 times larger than the full moon. ESA/Hubble & NASA, W. Blair

This image shows just one section of the Cygnus Loop, the remnants of a supernova blast located 1,500 light-years away, and despite this distance the loop is so large that it covers an area 36 times larger than the full moon. It is given its name because it is located near the Cygnus constellation, where is sits near one of the swan’s “wings.”

If you recognize the name Cygnus Loop, it may well be from another image taken by Hubble which we picked as one of the 10 best images the telescope captured since its launch. This is the Veil Nebula, another part of the same supernova remnant as the new image above, which was named for its delicate, draping appearance. Hubble had to take six different images and scientists arranged them into this mosaic to capture the nebula portion in all its glory:

This particular part of the loop is considered to be its own nebula, and this portion measures 110 light-years across in total. The line shape was formed by the shock wave of the supernova explosion, and it is wispy due to filaments of gas where the blast wave meets a region of cooler gas.

Hubble investigates the gorgeous remnants of a supernova
The Cygnus Loop nebula forms a bubble-like shape that is about 120 light-years in diameter.

Some of the most dramatic events in the universe are the deaths of massive stars. When stars far larger than our sun run out of fuel and explode in huge supernovas, these events not only let out huge blasts of energy but also change the environment around them. As the shockwave from the explosion travels outward millions of miles into space and slams into clouds dust and gas, it can create elaborate and beautiful structures called supernova remnants.

One of the most famous remnants is the Cygnus Loop, a bubble-shaped object which is around 120 light-years across. Hubble imaged the remnant in 2020, and now scientists are using this Hubble data to study how these remnants change over time.

Hubble captures a sparkling cloud galaxy located right next door
The galaxy ESO 300-16 looms over this image from the NASA/ESA Hubble Space Telescope.

An image from the Hubble Space Telescope shared this week by NASA shows a nearby galaxy, ESO 300-16. Unlike our Milky Way, which is a type called a spiral galaxy with a clear central bulge and defined spiral arms reaching out from its center, this neighborhood galaxy is loose and diffuse, looking more like a spattering of stars than anything with a clear structure. Hubble scientists describe it as a "sparkling cloud."

The galaxy is a type called an irregular galaxy, due to its lack of clear shape. Its stars clump together in a soft bubble form, and it is located nearly 29 million light-years away in the direction of the constellation Eridanus.

Hubble celebrates its 33rd birthday with stunning nebula image
Astronomers are celebrating the NASA/ESA Hubble Space Telescope’s 33rd launch anniversary with an ethereal photo of a nearby star-forming region, NGC 1333. The nebula is in the Perseus molecular cloud, and is located approximately 960 light-years away.

It will soon be the 33rd anniversary of the launch of the Hubble Space Telescope, and to celebrate this milestone, Hubble scientists have shared a stunning image taken by the telescope of a picturesque nebula. NGC 1333 is a busy stellar nursery, with new stars forming among the cloud of dust and gas located 960 light-years away.

The beautiful image of the nebula shows swirls of dark dust around glowing points of light where new stars are being born. To capture this scene, Hubble used its instruments across their full wavelengths, from ultraviolet through the optical light range and into the near-infrared. Hubble took the image using its Wide Field Camera 3 instrument, which used several filter across different wavelengths that were then assigned to colors (Blue: F475W, Green: F606W, Red: F657N and F814W) to create the colorful final result.
