![]() Shuttles aided in the construction of the International Space Station, launched the Hubble Space Telescope and carried interplanetary probes out of Earth’s atmosphere. It’s time to explore the universe… Floating over the Bahamas NASAīetween 19, the space shuttle program taxied a lot of power into (and out of) Earth’s orbit. With a small army of spacecraft and the most powerful telescopes in the world, NASA has captured some truly beautiful photos of outer space. And, more that six decades later, we still make new discoveries about our universe every day. July 29, 2021, marked the 63rd anniversary of NASA’s establishment. In the grand scheme of things, our exploration of the world outside Earth’s atmosphere began very recently. And Albert Einstein posited that space and time are intertwined in an infinite fabric stretching in all directions. Astrologers have searched for human meaning in the stars since at least the 3rd millennium BC. For thousands of years, we’ve charted and mythologized the cosmic mysteries of the night sky.Īncient Egyptians watched the star Sirius as an important part of calendar keeping. Appropriately, the proposal for observing time was named "They almost got away"! Astronomers took advantage of occasional gaps in Hubble's busy schedule to capture images of these barely-explored galaxy clusters, revealing a wealth of interesting targets for further study with Hubble and the NASA/ESA/CSA James Webb Space Telescope.Humans have looked to the stars since the dawn of civilization. This is one of a series of Hubble observations searching for massive, luminous galaxy clusters that had not been captured by earlier surveys. This collection of astronomical curiosities is the galaxy cluster ACO S520 in the constellation Pictor, which was captured by Hubble’s Advanced Camera for Surveys. A pair of bright stars are also visible at the left of this image, notable for their colourful criss-crossing diffraction spikes. As well as several large elliptical galaxies, a ring-shaped galaxy is lurking on the right of this image. Hubble recently completed a deep dive into jellyfish clusters, specifically …Ģ4 April 2023: A menagerie of interesting astronomical finds fill this image from the NASA/ESA Hubble Space Telescope. Unlike their ocean-dwelling namesakes, jellyfish galaxies make their homes in galaxy clusters, and the pressure of the tenuous superheated plasma that permeates these galaxy clusters is what draws out the jellyfish galaxies’ distinctive tendrils. These bright tendrils contain clumps of star formation and give jellyfish galaxies a particularly striking appearance. Jellyfish galaxies get their unusual name from the tendrils of star-forming gas and dust that trail behind them, just like the tentacles of a jellyfish. A handful of more distant galaxies are lurking throughout the scene, and a bright four-pointed star lies to the lower right side. ![]() This galaxy lies over 650 million light-years from Earth in the appropriately-named constellation Telescopium, and was captured in crystal-clear detail by Hubble’s Wide Field Camera 3. ![]() : The jellyfish galaxy JO175 appears to hang suspended in this image from the NASA/ESA Hubble Space Telescope. ![]()
