    What is your favourite Hubble Telescope image? NASA wants to know

    1/5 If you are interested in space, you must be excited about all the images shared by the various space telescopes. In 2022, NASA's Hubble Space Telescope has captured and shared several beautiful images. And NASA wants to know which one is your favourite Hubble Telescope image of 2022? In its latest Twitter post, NASA's Hubble Telescope has shared 4 images released in 2022 and has asked to vote for your favourite image. It can be known that the four images shared by the Hubble Space Telescope are of DEM L 190, NGC 976, HCG 40, and Terzan 2. (Hubble Space Telescope)

    2/5 DEM L 190, is a remnant from a massive star that died in a supernova blast whose light would have reached Earth thousands of years ago. This filamentary material will eventually be recycled into building new generations of stars. Our own sun and planets are constructed from similar debris of supernovae that exploded in the Milky Way billions of years ago, according to NASA. (Hubble Space Telescope)

    3/5 The galaxy NGC 976 lies around 150 million light-years from the Milky Way in the constellation Aries. Despite its tranquil appearance, NGC 976 has played host to one of the most violent astronomical phenomena known – a supernova explosion. These cataclysmically violent events take place at the end of the lives of massive stars and can outshine entire galaxies for a short period. While supernovae mark the deaths of massive stars, they are also responsible for the creation of heavy elements that are incorporated into later generations of stars and planets.

    4/5 The Hickson Compact Group 40 (HCG 40) is an unusual close-knit collection of five galaxies. This menagerie includes three spiral-shaped galaxies, an elliptical galaxy, and a lenticular (lens-like) galaxy. Somehow, these different galaxies crossed paths in their evolution to create an exceptionally crowded and eclectic galaxy sampler. Caught in a leisurely gravitational dance, the whole group is so crowded that it could fit within a region of space that is less than twice the diameter of our Milky Way's stellar disk.

    5/5 The Terzan 2 is a globular cluster in the constellation Scorpio. Globular clusters are stable, tightly gravitationally bound clusters of tens of thousands to millions of stars found in a wide variety of galaxies. The intense gravitational attraction between the closely packed stars gives globular clusters a regular, spherical shape. As a result, images of the hearts of globular clusters, such as this observation of Terzan 2, are crowded with a multitude of glittering stars. (Hubble Space Telescope)

    Water is the life force behind every living being on planet Earth. Without water, there is no life. Humans have been on the hunt for an Earth-like planet for decades. Space agencies like NASA, ISRO, CNSA and ESA use their extensive resources to search for planets which could support life one day, should the need to ever leave Earth arise. Although there are more planets in the Universe than you could ever imagine, they all have one substance missing which makes our Blue Planet so unique – Water, which is the elixir of life behind every living being on planet Earth.

    To search for habitable planets which could potentially support life, NASA launched its Transiting Exoplanet Survey Satellite (TESS) on April 18, 2018. According to NASA, TESS is an all-sky survey mission that will discover thousands of exoplanets around nearby bright stars. Since its launch, TESS has identified countless exoplanets, including a Super-Earth. One of them was even blanketed by water. Now TESS has made another astonishing discovery as it has found an Earth-sized planet in a habitable zone of its star with a high probability of water on the planet's surface, according to NASA.

    The planet is named TOI 700 e and it is part of a 3-planet system called TOI 700 b, c, and d. Although the 3 planets were discovered earlier, scientists had said they needed an additional year of TESS observations to discover TOI 700 e.

    The discovery was presented at the 241st meeting of the American Astronomical Society in Seattle and A paper about the planet was accepted by the Astrophysical Journal Letters. Emily Gilbert, a postdoctoral fellow at NASA's JPL in Southern California who led the work said in a NASA blog, “This is one of only a few systems with multiple, small, habitable-zone planets that we know of. That makes the TOI 700 system an exciting prospect for additional follow-up.”
