Hubble serves up two views of Lagoon Nebula

Hubble serves up two views of Lagoon Nebula

Science
April 19 (UPI) -- The Hubble Space Telescope celebrated its 28th anniversary with a double portrait of the Lagoon Nebula, a giant, oft-photographed interstellar cloud.The juxtaposed images, released Thursday by NASA, showcase the emissions nebula in two different spectral bands: one in visible light and the other rendered in near-infrared.The visible-light image showcases the nebula's gas and dust, while the near-infrared photograph reveals the multitude of stars found within.The two images reveal the two ingredients that make nebulas what they are: star-forming material and stars.Gas and dust are essentials to stellar formation, and as they fuel the formation of new stars, stellar winds contort the surrounding star-forming materials into a variety of textures and shapes -- nobs, columns, ...
Hubble captures glow of giant galaxy cluster

Hubble captures glow of giant galaxy cluster

Science
April 13 (UPI) -- A new image from the Hubble Space Telescope showcases a massive galaxy cluster, a web of thousands of galaxies tied together by the tug of gravity.The galaxy cluster featured in the image is named PLCK G308.3-20.2. Like an ecosystem full of biodiversity, the cluster is home to wide range of galaxies -- all different types, shapes and sizes.This particular galaxy cluster is situated 5 billion light-years away from Earth.As recently as a few decades ago, astronomers thought galaxy clusters were the largest structures in the universe, but in the 1980s, scientists realized galaxy clusters were organized into structures called superclusters.Superclusters are made of groups of clusters that can stretch hundreds of millions of light-years across. Some superclusters cover as much...
Hubble spots Einstein ring surrounding galaxy cluster

Hubble spots Einstein ring surrounding galaxy cluster

Science
April 6 (UPI) -- A new image from Hubble showcases dozens of distant galaxies, as well as an astronomical phenomenon known as an Einstein ring.The lens-like circle at the image's center represents the distortion caused by the gravity of a galaxy cluster named SDSS J0146-0929. The cluster is comprised of millions of galaxies, all tied together by the pull of gravity.The gravity of the cluster's millions of galaxies is strong enough to warp the surrounding space-time.As distant light travels toward Earth, it bends around the massive cluster, creating the lens-like phenomenon."In this image, the light from a background galaxy is diverted and distorted around the massive intervening cluster and forced to travel along many different light paths toward Earth, making it seem as though the galaxy ...
JWST: Hubble 'successor' faces new delay

JWST: Hubble 'successor' faces new delay

Science
The successor to the Hubble Space Telescope has been delayed yet again and will not now launch until "approximately May 2020".The James Webb Space Telescope is also in danger of busting the cost cap put on the project by the US Congress.Back in 2011, politicians on Capitol Hill said the observatory should not take more than $ 8bn to build and $ 800m to operate over five years in orbit.US space agency officials now say the construction bill could exceed the cap."To date, Nasa has invested $ 7.3bn in Webb; Webb's development costs are about $ 8bn total and the maximum allowable level established by law," explained Acting Nasa Administrator Robert Lightfoot. "If we breach the $ 8bn cost laid out in the Congressional appropriations, the project will need to be re-authorised by Congress."JWST i...
Watch: Hubble video offers 3D tour through the Orion Nebula

Watch: Hubble video offers 3D tour through the Orion Nebula

Science
Jan. 19 (UPI) -- Want to take a virtual ride through the Orion Nebula? Hubble has the ticket.Scientists at Hubble used visible and infrared light data to create a 3D journey through the famed nebula. Visible light observations were captured by the Hubble Space Telescope and infrared data was observed by the Spitzer Space Telescope.Scientists first combined the two datasets to create 2D images and then converted the images into a 3D video."As the camera flies into the star-forming region, the sequence cross-fades back and forth between the visible and infrared views," scientists wrote in the video's caption. "The glowing gaseous landscape has been illuminated and carved by the high energy radiation and strong stellar winds from the massive hot stars in the central cluster."Infrared data, wh...
