Arp 122 Is Two Different Galaxies Getting Ready To Collide

The photo above is a galaxy known as Arp 122, which shows two different galaxies getting ready to collide. The two galaxies are NGC 6040, as well as LEDA 59642.According to NASA, this encounter is happening about 570 million light-years from earth. On the bottom right of the image is the elliptical galaxy NGC 6041, a part of the galaxy cluster than Arp 122 resides in. However, this isn't part of the merger we can see in the right part of the image.These galaxy collisions are very dramatic, but they take awhile. Our own milky way will eventually collide with the Andromeda Galaxy, which will happen about 4 billion years from now.The same idea goes for Arp 11 - we won't exactly know when it will collide, but it will definitely be a very long time from now.Image Source: ESA/...

The Furthest Known Fast Radio Burst Is Home To Seven Galaxies

Using NASA's Hubble Space Telescope, astronomers have found a fast radio burst. What's weird about this is they found it erupted halfway across the universe, making it the farthest and most powerful ever detected.The fast radio burst (FRB) also got even weirder based on the follow up Hubble observations. The FRB flashed in what seems like a strange place: a collection of galaxies that existed when the universe was only 5 billion years old. Normally, astronomers find these in isolated galaxies.The FRB is being called FRB 20220610A, and it was first detected by the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope. After that, the European Southern Obsevatory's Very Large Telescope in Chile confirmed it came from a distant place.The images taken by Hubble sugg...

Hubble Telescope Observes Exoplanet Called WASP-121 B

Over thee last three years, NASA's Hubble Space Telescope has been watching a planet known as WASP-121 B. Located about 880 light years away, the exoplanet is a non-habitable exoplanet the size of Jupiter.On the exoplanet, astronomers have found evidence of massive cyclones and storms, as well as other dynamic weather activity. These storms and cyclones repeatedly created due to the large temperature difference between the star -facing side and the dark side of the exoplanet. They also detected an apparent offset between WASP-121 B's hottest region, and the point closest to the star.WASP-12 B is very close to its parent star, making is orbital period only 1.27 days. This means the planet is tidally locked, so that the same hemisphere always faces the star. Daytime temperatures ar...

Hubble Found A Seyfert Galaxy Which Has ‘ Forbidden Light ‘

It seems like everyday the Hubble Space Telescope is making new discoveries. Recently, the space telescope took a look at a Seyfert galaxy, known as MCG-01-24-014. What it found was a type of forbidden light, which shouldn't be there.Located about 275 million miles away from Earth, the galaxy has two spiral arms and n energetic core known as a active galactic nucleus (AGN). It's categorized as a Seyfert Galaxy, which host the most common sub classes of AGNs. According to NASA, Seyfert Galaxies have two different subcategories.Both are distinguished by their spectra, which is the pattern that results when light is split into constituent wavelengths. Type 2 Seyfert Galaxies emit spectral lines, which are associated with the forbidden emission lines Hubble detected. Spectra look like...

NASA Captures Breathtaking Image of NGC 2210

It seems like the Hubble Space Telescope will always be a part of our lives, even if James Webb is more powerful. Today, NASA has shared a new photo of the globular cluster NGC 2210 galaxy, which was taken by Hubble.NGC 2210 is situated in the Large Magellanic Cloud (LMC), which is about 157,000 light years from us. It's a satellite galaxy of the milky way, meaning the two galaxies are locked with gravity. Globular cluster are stable, tightly bound clusters of millions of stars. They can last a long time, and researchers even believe this galaxy is about 11.6 billion years old.Considering the age of the universe, this means the galaxy is only a couple of billion years younger than the universe itself.Image Source: ESA/Hubble & NASA, A.

Hubble Celebrates 30th Anniversary of It’s 1st Servicing Mission

Ever since it's first debut in April 24, 1990 the Hubble Space Telescope has been providing us with some astonishing views. The Hubble telescope was responsible for delivering us that famous image of the Pillars of Creation, as well as many others.However, the journey to this wasn't easy. Back when Hubble was launched, it had a defect - it couldn't see straight. It had a flaw in it's primary mirror, which was fixed in it's 1st servicing mission. On December 2, 1993, the space shuttle Endeavour launched from the Kennedy Space Center to fix the telescope.https://www.youtube.com/watch?v=2X0Hghl3SYkWhen the astronauts arrived at Hubble, they were able to slide in new components to fix the problem. They swapped out both the Wide Field and Planetary Camera (WFPC2) as well as the C...

Astronomers Study Nearby Pulsar Called B1055-52

Astronomers recently conducted an in-depth study of the pulsar B1055-52 using advanced satellites and telescopes. Pulsars, such as B1055-52, are highly magnetized rotating neutron stars that emit electromagnetic radiation. While commonly detected through radio telescopes, this pulsar's unique characteristics allowed for observations in optical, X-ray, and gamma-ray wavelengths.Previous research suggests that B1055-52 is located within a distance of approximately 2,300 light years from Earth. With a spin period of 197 milliseconds, a spin-down age of about 535,000 years, and a spin-down power of 30 decillion erg/s, B1055-52 possesses an intense surface magnetic field at 1.1 TG.To better understand B1055-52's X-ray spectral parameters and fluxes, a team of astronomers, led by Bettin...

JO206: The Enchanting Jellyfish Galaxy Revealed by Hubble

Witness the awe-inspiring jellyfish galaxy JO206 as it glides across this captivating image from the NASA/ESA Hubble Space Telescope. The vibrant star-forming disk of JO206, encircled by a delicate and luminous dust cloud, takes center stage. Against a dark backdrop, a few prominent foreground stars with mesmerizing diffraction spikes catch our attention at the bottom of the image. Located in the constellation Aquarius, JO206 resides an astonishing distance of over 700 million light-years away from Earth.Jellyfish galaxies get their name from their striking resemblance to the graceful marine creatures. In this image, you can see long tendrils of bright star formation trailing behind JO206's disk, reminiscent of the tentacles trailing behind a jellyfish.These distinctive tendrils a...

Hubble Space Telescope Captures Image of Two Distant Galaxies

Recently, astronomers celebrated the 33rd launch anniversary of the Hubble Space Telescope. Launched back in 1990, the telescope provides us with amazing views and images.The image shown is taken by Hubble, and it shows us two distant galaxies. On the left, we see a tilted galaxy known as NGC 4302 On the right, we see another galaxy called NGC 4298. These galaxies reside in the constellation Coma Berenices, which are 55 million light years away from us. Both of these galaxies were discovered by William Herschel in 1784.Both of these galaxies are very similar - they are spiral galaxies which have arms of young stars that wind outward from the center. The bright arms are areas of strong star formation, and they have central bulges surrounded by a faint halo of stars and bars that e...
