    Top NASA Astronomy Pictures of the Week: Crescent Moon, Flaming Nebula, Venus to Jupiter
    Venus and Jupiter conjunction
    1/5 Venus-Jupiter Conjunction (Feb 27) - features the view of Venus and Jupiter, but with an unusual ray of light extending from the horizon. It is known as Zodiacal light, a band of dust reflecting sunlight from the inner Solar System which becomes noticeable during certain periods when observed after sunset or before sunrise.

    crescent Moon
    2/5 Crescent Moon and the Temple of Poseidon (Feb 28) - It is a stunning snapshot of the thin crescent Moon with the ancient Greek Temple of Poseidon at the forefront in Greece. According to NASA, the moonlight we see on Earth is sunlight reflected off the Moon's grayish-white surface. (NASA/Elias Chasiotis)
    Flaming Star Nebula
    3/5 Flaming Nebula, Tadpole Nebula and Comet ZTF (March 1) - Flaming Star Nebula and the Tadpole Nebula can be seen crossing paths with the Comet ZTF. IC405, otherwise known as the Flaming Star Nebula, lies about 1,500 light-years away toward the constellation of Auriga and spans about 5 light-years across.  (NASA/Thomas Roell)
    nasa spiral galaxy
    4/5 Spiral Galaxies NGC 3169 and NGC 3166 (March 2) - It is a stellar snapshot of Spiral Galaxy NGC 3169 and its neighbour NGC 3166. NGC 3169 is located almost 70 million light-years away in the constellation of Sextans (the Sextant). According to NASA, it is part of the Leo I Group of galaxies which is part of a larger galactic congregation known as the Virgo Supercluster.  (NASA/Mike Selby/Mark Hanson)
    NASA supernova remnant
    5/5 Supernova Remnant RCW 86 (March 3) - After the supernova explosion, its remnants are left behind, which are known as Supernova Remnants (SNR). NASA’s Astronomy Picture of the Day is an extremely rare and historical snapshot of Supernova Remnant RCW 86 which spans around 100 light-years and is located nearly 8000 light-years away.  (NASA/CTIO/NOIRLab/DOE/NSF/AURA)

    Here is all you need to know about the jellyfish galaxy clicked by the Hubble Space Telescope. (ESA/Hubble & NASA, M. Gullieuszik)

    From galaxies, Sun, planets, to asteroids, meteors, and more, space is virtually infinite. These objects are of different sizes and shapes. Have you heard of a jellyfish galaxy? Yes, it exists! A jellyfish galaxy with trailing tentacles of stars hanging in inky blackness has been clicked by NASA's Hubble Space Telescope. Sharing the image of the same Hubble tweeted, "This image shows a "jellyfish" galaxy called JO201. As jellyfish galaxies move through space, gas is slowly stripped away – forming trails that look like tendrils illuminated by clumps of star formation!"

    Hubble's Wide Field Camera 3 (WFC3) captured this galactic seascape. "A versatile instrument that captures images at ultraviolet, infrared, and visible wavelengths, WFC3 is the source of some of Hubble's most spectacular images," NASA informed.

    Describing the image, the research organisation said, "These blue tendrils are visible below the core of this galaxy, giving it a jellyfish-like appearance. This particular jellyfish galaxy – known as JO201 – lies in the constellation Cetus, which is named after a sea monster from ancient Greek mythology. This sea-monster-themed constellation adds to the nautical theme of this image."

    The tendrils of jellyfish galaxies extend beyond the bright disk of the galaxy's core. This particular observation comes from an investigation into the sizes, masses, and ages of clumps of star formation in the tendrils of jellyfish galaxies.

    How can jellyfish galaxies help astronomers

    Astronomers hope this will provide a better understanding of the connection between ram-pressure stripping – the process that creates the tendrils of jellyfish galaxies – and star formation.

    Hubble Space Telescope

    Hubble, the observatory, is the first major optical telescope to be placed in space. It was launched and deployed in April 1990 marking the most significant advance in astronomy since Galileo's telescope. Scientists have used Hubble to observe the most distant stars and galaxies as well as the planets in our solar system.
