ABOUT Hubble Space Telescopefrom NASA managed to observe the most distant single star ever seen in the universe. The feat happened this week on Thursday (30), allowing the telescope to break its own record for recognizing celestial bodies in vast space. According to NASA calculations, Hubble detected light from a star that existed 900 million years after the emergence of the Universe, in the Big Bang – it is at a distance of 28 billion light years and can be 50-500 times more massive than the Sun of our solar system.
Hubble has been roaming the universe for over 30 years to discover what lies beyond our galaxy. The unmanned artificial satellite was launched by NASA on April 24, 1990, and to this day it has succeeded map of over 265,000 galaxies. The telescope was the first NASA mission owned by the Great Space Observatories and allowed people (for the first time) to study in much greater detail the structures of the universe, hitherto unknown or little observed.
Images of the Universe – Official website of the Hubble Space Telescope
To celebrate the Hubble Telescope’s new record, we’ve rounded up 20 amazing images it’s taken during its 30 years of space adventure.
This mosaic includes infrared, optical and ultraviolet data that show a wide and deep view of space. In 2019, astronomers collected 7,500 images taken by Hubble over 16 years of observations and collected 265,000 galaxies in the area known to the telescope.
In 2022, the star V838 Monocerotis, located in the constellation Monoceros (or Monoceros), suddenly flared up and then disappeared. Years later, astronomers returned to observe it and found an expanding shell of gas around it, likely indicating that an explosion had occurred.
The image shows an optical illusion of Stephen’s Quintet, a visual group of five galaxies located in the constellation Pegasus. At first glance, it looks like five galaxies collided. However, only three actually interact, and the bright galaxy in the upper left corner is seven times closer to Earth than the rest.

The Sombrero Galaxy (M104) is one of Hubble’s brightest images due to its bright disk surrounded by a ring of dust. Its features are hard to discern when we see it from the side, but astronomers have used this Hubble image to identify 2,000 star clusters in and around the galaxy.
All stars, including our Sun, produce “wind” in the form of electrically charged particles on their surfaces. The star at the center of the Bubble Nebula (45 times as massive as the Sun) has a great shape and color to see due to its wind colliding with gases.
Galaxy collisions may seem violent, but they are one of the main ways that small galaxies turn into larger ones as they merge. And, without a doubt, galactic collisions are beautiful. The captured image of a pair of galaxies Arp 273 shows star formation stimulated by the interaction of these galaxies.
The Milky Way is one of three large galaxies in a small cluster known as the Local Group. The other two are Andromeda (the largest of the group) and Triangulum (M33), a small spiral that rapidly creates new stars, which intrigues astronomers.
The Large Magellanic Cloud is the largest satellite galaxy of the Milky Way, hosting supernova 1987A. It also hosts a massive star-forming region known as the Tarantula Nebula, which was captured by Hubble’s infrared camera. The image shows 800,000 stars and protostars within the region.
The two galaxies that make up Arp 142 collided, and their gravity eventually formed a shape similar to a galactic penguin. This penguin was once a spiral galaxy like ours, but the encounter changed its shape and increased the production of new stars.
The Southern Pinwheel Galaxy (M83) is a “flaky” spiral galaxy, meaning that its spiral arms look fluffy due to the large amount of gas and dust they contain. This high-resolution image shows star formation and cavities where stars have exploded and gone supernovae.
During a mission to observe the deep universe, the Hubble Space Telescope observed a relatively empty patch of sky for about 1 million seconds (nearly 12 full days). This longest exposure revealed 10,000 galaxies, including some of the most distant ones ever discovered.
The Ring Nebula is located 2300 light years from Earth in the constellation Lyra. From this angle, the image shows a white dot at the center of the nebula. The dot is a white dwarf, a stellar remnant of the core of the original star.
The Whirlpool Galaxy (M51), as the name suggests, is a well-defined spiral galaxy. It has bright blue stars and pink clouds (the area where new stars form). Gravitational interactions with the smaller galaxy are likely causing this star formation, shown on the right side of the image.
The bright light in the lower left corner of the image is supernova 1994D on the outskirts of the galaxy NGC 4526. This is a type Ia supernova, a white dwarf explosion. Astronomers use Type Ia supernovae to measure the expansion of the universe, as they are bright enough to be seen billions of light years away.
RS Puppis is a Cepheid variable star (aging pulsating stars with predictable light fluctuations) about 5577 light-years from Earth. It is one of the largest and brightest known Cepheids in the Milky Way.
The Horsehead Nebula in the constellation of Orion is one of the most popular sighting spots for those with backyard telescopes. This infrared image from the Hubble Space Telescope shows newborn stars hidden in the gas of the nebula.
In early 1987, astronomers discovered a new point of bright light in a nearby galaxy in the Large Magellanic Cloud. The point is cataloged as Supernova 1987A, the explosion of a massive star and the closest supernova to present day. Astronomers have been able to track the aftermath of the explosion in a Hubble image showing bubbles of expanding matter exploding, creating points of light in the area nearby where the material collided with the gas clumps.
Antenna galaxies are a pair of colliding galaxies, a slow process that takes hundreds of millions of years. This image combines images from NASA’s Great Observatories – Hubble (visible light), Spitzer Infrared Observatory (infrared), and Chandra X-ray Observatory (X-rays).
The dense gas and dust of the Eagle Nebula are opaque to visible light, but transparent to infrared radiation. Hubble’s infrared image of the Pillars of Creation shows that they contain very young stars shrouded in gas.
This image of Jupiter, taken by Hubble in 2017, is part of the telescope’s program to map changes in the atmospheres of the outer giant planets. In particular, astronomers are watching Jupiter’s famous Great Red Spot shrink.
