HubbleESA: How many galaxies are there?

A new study using the Hubble Space Telescope and other telescopes has increased the estimate of galaxies in the Universe ten fold. It was previously estimated that there was 100 billion galaxies in the observable Universe. The researchers used deep space images from the Hubble Space Telescope. They converted images to 3D and applied new …

VOX: The 1995 Hubble photo that changed astronomy

The Hubble Deep Field, explained by the man who made it happen. One of the main scientific justifications for building Hubble was to measure the size and age of the Universe and test theories about its origin. Images of faint galaxies give ‘fossil’ clues as to how the Universe looked in the remote past and …

Hubble Space Telescope: Zoom Into the Center of Our Galaxy

This video sequence zooms into the Hubble Space Telescope view of the galactic core. Hubble’s infrared vision pierced the dusty heart of our Milky Way galaxy to reveal more than half a million stars at its core. Except for a few blue, foreground stars, the stars are part of the Milky Way’s nuclear star cluster, …

NASA: Hubble Team Breaks Cosmic Distance Record

This animation shows the location of galaxy GN-z11, which is the farthest galaxy ever seen. The video begins by locating the Big Dipper, then showing the constellation Ursa Major. It then zooms into the GOODS North field of galaxies, and ends with a Hubble image of the young galaxy. GN-z11 is shown as it existed …

NASA: Nick Siegler | Planet Hunting

The Search for Planets, Habitability, and Life in our Galaxy What will the first evidence of life outside our own solar system look like? And what future technologies are required to discover that evidence? Exoplanet-hunting space-borne telescopes must suppress the bright glare from stars up to ten billion times in order to directly image the …

AMNH: Science Bulletins | Hubble Space Telescope—25 Years and Counting

Few of NASA’s telescopes have captured the public imagination like Hubble, with its spectacular views of distant galaxies, supernovas, and nebulas. The first telescope in the world to return visible wavelength images of space from near Earth orbit, Hubble’s photos are more than just pretty pictures. In its twenty-five year mission, Hubble’s discoveries have transformed …

Nature Video: Robert Kirshner | Hubble moments

Robert Kirshner was part of the supernova team that used Hubble to discover the accelerating expansion of the universe which led to a 2011 Nobel Prize for his students. Iin this Nature Video, Kirshner tells us his favourite Hubble moment: a particular supernova which sparked his imagination, 1987A.  

NASA’s Documentary Film: Hubble25

In its quarter-century in orbit, the Hubble Space Telescope has transformed the way we understand the Universe, helped us find our place among the stars, and paved the way to incredible advancements in science and technology. The Hubble story is a human story. Hubble overcame much adversity early on in its mission and demonstrated the …

NASA: Hubble | Expect the Unexpected

NASA’s Hubble Space Telescope is one of the most powerful scientific instruments ever conceived. Hubble’s most important discoveries have provided answers to questions that astronomers did not yet know how to ask, and found objects that were not yet imagined. This installment of the “Hubble at 25” series looks at how Hubble far exceeds its …

HubbleESA: Time-lapse of Jupiter’s three moon transit

These new NASA/ESA Hubble Space Telescope images capture a rare occurrence as three of Jupiter’s largest moons parade across the giant gas planet’s banded face. Hubble took a string of images of the event which are stitched together to show the three satellites — Europa, Callisto and Io — in action in this time-lapse video. …

NASA: Water found in the atmospheres of 5 alien planets

Scientists say they have found evidence of water on five planets outside our solar system; WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b.. They have been using the Hubble Space Telescope, to study these planets they call “hot Jupiters,” they are massive worlds that orbit close to their stars. Nasa writes in a press release that the presence …
