  1. NGC 2371
    The object, called NGC 2371, is a planetary nebula, the glowing remains of a sun-like star. The remnant star visible at the center of NGC 2371 is the super-hot core of the former red giant.

    Was Hubble able to spot circumstellar material before a supernova?
    Hubble was able to spot circumstellar material around the star shortly after the explosion. The aging star releasedthis material in the final year before its death, allowing astronomers a glimpse into what happened prior to the supernova. This illustration shows a massive star that is about to explode.

    What does Hubble's vision reveal about a planetary nebula?
    Hubble's extraordinary vision reveals that it is one of the most elongated planetary nebulae found so far. The image shows two very long cylindrical outflows with intricate thread-like structures and tattered ends. We are seeing the central star responsible for the beautiful display for the first time in this image.

    How bright is the Hubble Nebula?
    As a variable star, its apparent brightness swings wildly, between 5.7 and 9, adding to the difficulty. It’s no problem for the Hubble though. The nebula itself contains about 15 solar masses of material. Some of that was ejected from the star about 10,000 years ago.

    Why is the Hubble Nebula so difficult to see?
    It’s difficult to see, both because of its distance and because it’s obscured by dust in visible light. As a variable star, its apparent brightness swings wildly, between 5.7 and 9, adding to the difficulty. It’s no problem for the Hubble though. The nebula itself contains about 15 solar masses of material.

    Which star has a violent outburst?
    This ultraviolet light observation of the giant Eta Carinae star was taken by Hubble in 2019. The star is the larger out of two that orbit each other. It's known to have violent outbursts, as evidenced by the bubbles here. NASA Fireworks are even more beautiful in space. Hubble captured this image of a giant cluster of 3,000 stars in 2015.

    When was the Hubble Space Telescope launched?
    The Hubble Space Telescope was launched from the space shuttle Discovery on April 24, 1990. NASA Hubble has given us many images of our neighbor Mars. This image was taken in 2003 when Mars made its closest approach in nearly 60,000 years. On August 27, 2003, the two worlds were only 34.6 million miles apart from center to center.
