The unusual sight was captured using the Nasa/ESA Hubble Space Telescope with the aim of giving scientists a better understanding of the early universe. NASA/ESA/Hubble/AFP via Getty Images Galaxy optical illusionĪstronomers spotted a galaxy in the distant universe which appears duplicated on the night sky at least 12 times. An enormous “mega-storm” is seen swirling above Jupiter’s surface. The so-called Great Red Spot is wider than the Earth, with furious winds reaching speeds of up to 425mph. This stunning photo of Jupiter clearly shows an enormous “mega-storm” swirling above the surface. It spans 4 to 5 light-years of the nebula, which is about 70 by 55 light-years wide.Ī nebula is just a large cloud of dust and gas in space. It’s called the Pillars of Creation and shows a small section of the Eagle Nebula. Nasa’s Hubble Space Telescope captured this image in 1995. The images and data Hubble has collected so far have changed and enhanced our understanding of the cosmos. Over the past three decades, the Hubble telescope has been beaming amazing images of space back to Earth. The James Webb telescope will one day succeed the Hubble but it will have a hard job replacing some of the most amazing space images taken by the older craft. You may have seen the James Webb Space Telescope discussed a lot this week but the Hubble Space Telescope was once the most iconic. ![]() ![]() Millions of asteroids could make you richer than Elon Musk Giant asteroid three times as big as Statue of Liberty to ‘skim’ past Earth Scientists baffled after recording ‘eerie sounds’ coming from Jupiter’s moon Where is the James Webb space telescope RIGHT NOW? It seems reasonable to think it took a few months though.NASA launches alien-hunting James Webb space telescope But note that these are not raw image files as sent by Hubble. Note that the article linked below says that Hubble doesn't in fact send data to Earth - instead it sends it to the geosynchronous tracking and data relay satellite system (TDRSS) twice a day, which will add some delays.Īnd I just found this cool picture (source):Īs for the size of the Andromeda data (the Panchromatic Hubble Andromeda Treasury), you can start at and dig down to the data files from there - for example, when you drill down to brick 1, you will come to and you'll see a long, long list of files that amounts to about 94 GB of data. From the furthest point it will be about 4000 km away, so it would take 13 ms for the signal to reach earth (speed of light ~300,000 km/s). The time for the radio signal to travel back to earth depends on the distance to the transmitter, but since its orbit is only 569 km above the earth's surface, it could be as little as 2 ms. Even so, a single image from the Hubble takes very little time to transmit - but depending on which composite image (dataset) you are talking about, the answer could be "a very long time". Today, it uses WFC3 - a 8 mega pixel camera. One picture of the original camera was only 640k pixels (this camera was built a long time ago), but the images you see are composited from many many images. Hubble transmits about 120 GB of data per week (source: ). ![]()
