Hubble Space Galaxy Shares Photo of Peculiar Galaxy and Earth-Like Exoplanet

Scientists using the Hubble Space Telescope shared two stunning space images. One is a curiously asymmetrical galaxy in the Pegasus constellation. A rocky exoplanet with a regenerated atmosphere is number two.

NGC 7678
This image taken with the NASA/ESA Hubble Space Telescope features NGC 7678 – a galaxy with one particularly prominent arm, located approximately 164 million light-years away in the constellation of Pegasus (the Winged Horse). With a diameter of around 115,000 light-years, this bright spiral galaxy is a similar size to our own galaxy (the Milky Way) and was discovered in 1784 by the German-British astronomer William Herschel.

Unless they have undergone a catastrophic occurrence such as a collision with another galaxy that has pulled them into an odd shape, most galaxies, like our own Milky Way, are broadly symmetrical.

However, the Hubble Space Telescope has been seen to share multiple galaxies on occasion.

Hubble Space Telescope Has Released Its First Image: NGC 7678

NGC 7678 is included in the first photograph taken with the NASA/ESA Hubble Space Telescope. According to SpaceRef, it's a galaxy with one famous arm that's about 164 million light-years away in the constellation Pegasus (the Winged Horse).

This brilliant spiral galaxy, which has a diameter of about 115,000 light-years and was discovered in 1784 by the German-British astronomer William Herschel, is close in size to our own galaxy (the Milky Way).


The Atlas of Peculiar Galaxies is a catalog created by American astronomer Halton Arp in 1966. NGC 7678 is one of 338 galaxies included in this catalog, which classes strange galaxies by their unusual characteristics. Arp 28 is one of six spiral galaxies with one heavy arm that make up the group "spiral galaxies with one heavy arm."

According to Digital Trends, one of the weapons in this galaxy has far more matter than the others. It is much more massive, which is why it is brighter, and more stars are forming there. It stands out from other galaxies, including our own, because of this distinguishing characteristic.

Hubble Space Telescope Shares Its Second Image: An Exoplanet That Regenerates Atmosphere

The Hubble Space Telescope has also helped to discern seismic activity on the planet GJ 1132 b, which is 41 light-years away from our solar system and has a designation of GJ 1132 b. This is the first time scientists discovered a secondary atmosphere on a planet outside of our solar system.

Raissa Estrella, a co-author of the analysis at NASA's Jet Propulsion Laboratory in Pasadena, California, said in a statement that these heavily radiated planets would be "pretty dull" because they would have lost their atmospheres. The mood, on the other hand, has been revitalized.

Paul Rimmer of the University of Cambridge said per Gent Side that the new observation offers scientists working on exoplanets a way better to describe a planet's geology from its atmosphere. This secondary atmosphere, he explained, is a gateway into the geology of another world since it emerges from both the surface and the planet's interior.

Both GJ1132 b and the Earth have certain similarities: they have identical densities, sizes, and ages, and they are believed to have had a hydrogen-dominated atmosphere that was heated before cooling. Astronomers assume they could have the same air pressure on their surfaces, based on their studies.
