Hubble Uncovers Faint Stars in the Core of Globular Cluster
These comparison images of the core of the globular cluster 47 Tucanae (NGC104) were taken with the COSTAR Corrected Faint Object Camera to show the improvement In performance when compared to images taken with the uncorrected camera.
Hubble Probes the Great Orion Nebula
A NASA Hubble Space Telescope image of a region of the Great Nebula in Orion, as imaged by the Wide Field Planetary Camera 2. This is one of the nearest regions of very recent star formation (300,000 years ago). The…
Hubble Observes a Star On the Brink of Destruction
A NASA Hubble Space Telescope “natural color” image of the material surrounding the star Eta Carinae, as imaged by the Wide Field Planetary Camera 2 (WFPC-2). The Camera was installed in the Hubble Space Telescope during the STS-61 Hubble Servicing…
Comparative View of a Star Before and After the Installation of the Corrective Optics Space Telescope Axial Replacement (COSTAR)
This pair of images of a single star, taken with the European Space Agency’s Faint Object Camera (FOC), demonstrate that NASA’s Hubble Space Telescope has been restored fully to its planned optical performance. The COSTAR mirrors remove the effect of…
The Spiral Galaxy M100 as Seen With the Hubble’s Improved Vision
An image of the grand design spiral galaxy M100 obtained with the second generation Wide Field and Planetary Camera (WFPC-2), newly installed in the Hubble Space Telescope. Though the galaxy lies several tens of millions of light-years away, modified optics…
HST Reveals the Central Region of an Active Galaxy
The refurbished HST has provided this outstanding image of the nuclear region of the galaxy NGC 1068. NGC 1068 is located at a distance of approximately 60 Million Light Years and is the prototype of a class of galaxies, known…
Hubble Sees Changes in Gas Shell around Nova Cygni 1992
The Hubble telescope has given astronomers their best look yet at a rapidly ballooning bubble of gas blasted off a star. The shell surrounds Nova Cygni 1992, which erupted Feb. 19, 1992. A nova is a thermonuclear explosion that occurs…
Hubble Space Telescope Images of a Bright Star in the Large Magellanic Cloud
These three images are of a very bright (Wolf-Rayet) star, Melnick 34, located in the giant star-forming region called 30 Doradus in the Large Magellanic Cloud. In the background are a number of fainter stars that are comparable in brightness…
Hubble’s Improved Optics Reveal Incredible Detail in Giant Cloud of Gas and Dust
An image of a star-forming region in the 30 Doradus nebula, surrounding the dense star cluster R136. The image was obtained using the second generation Wide Filed and Planetary Camera (WFPC-2), installed in the Hubble Space Telescope during the STS-61…
Galaxy M100 Resolution Comparison
This sequence of pictures shows successive steps in optical improvement from ground based telescopes to the newly improved Hubble Space Telescope and demonstrates the unique capability of the repaired HST. HST offers superb resolution, which allows astronomers to distinguish individual…
Picture Perfect: Hubble’s New Improved Optics Probe the Core of a Distant Galaxy
This comparison image of the core of galaxy M100 shows the dramatic improvement in the Hubble telescope’s view of the universe. The new image (right) was taken with the second generation Wide Field and Planetary Camera (WFPC2), which was installed…
Hubble Space Telscope Deep-sky Survey Finds Interacting Galaxies in a Cluster
In one of the deepest celestial surveys yet made by NASA’s Hubble Space Telescope, astronomers have discovered a small group of previously unknown, interacting galaxies estimated to be three billion light-years away.* Hubble caught the galaxies in an early stage…
Hubble Investigates Comet on a Collision Course with Jupiter
NASA’s Hubble Space Telescope has provided the most detailed look yet at the comet hurtling toward a July 1994 collision with the giant planet Jupiter. Hubble’s high resolution shows that the approximately 20 objects that comprise comet P/Shoemaker-Levy 9- giving…
Hubble Sees Gas Shell Around Nova Cygni 1992
NASA’s Hubble Space Telescope (HST) has given astronomers their earliest look at a rapidly ballooning bubble of gas blasted off a star. The shell surrounds Nova Cygni 1992, which erupted February 19, 1992. A nova is a thermonuclear explosion that…
HST Snaps Optical Jet of Quasar 3c 273
The Green (V band) image (left) shows the field around the quasar 3c 273 (courtesy Matthew Colless, David Schade and the CFHT). The optical jet can be seen southwest of the quasar. The blue (B band) image (right) shows the…
Core of the Globular Cluster NGC 6624
This is a comparison of pictures of the core of the globular cluster NGC 6624, as imaged with the European Space Agency’s Faint Object Camera aboard NASA’s Hubble Space Telescope. This comparison image demonstrates that Hubble’s high resolution and ultraviolet…
Hubble Space Telescope Finds a Double Nucleus in the Andromeda Galaxy
A team of astronomers using NASA’s Hubble Space Telescope has discovered a “double nucleus” in the center of the neighboring spiral galaxy M31, located in the constellation Andromeda. “Hubble shows that the M31 nucleus is much more complex than previously…
Hubble Observations Support Black Hole Explanation For Active Galaxies
A team of astronomers reports that recent NASA Hubble Space Telescope (HST) observations of the nearest Seyfert galaxy, NGC 4395, further support the theory that active galaxies are fueled by a massive black hole at the center. The researchers say…
Comparison of a WFPC2 Thermal Vacuum Globular Cluster-Mask Image to Wfpc1
After NASA Hubble Space Telescope’s refurbishment to correct spherical aberration, its resolution for imaging stars is expected to increase by a factor of 10-15 over ground-based, and a factor of 2-3 over the pre-reburbished Hubble. The expected improvement in resolution…
HST Reveals Stunning Detail in Herbig-Haro Object
NASA’s Hubble Space Telescope (HST) has provided astronomers with their clearest look yet at a vast cloud of gas being heated by the birth of a new star. The results from this observation are being presented to the American Astronomical…
Hubble Takes Major Step in Determining the Age of the Universe
A team of astronomers working with NASA’s Hubble Space Telescope announced results today of a major step in the Key Project to measure the Hubble Constant and the age of the universe. The team has discovered variable stars in its…
A Lighthouse Beacon From the Core of an Active Galaxy
A NASA Hubble Space Telescope (HST) view of the core of the barred spiral Seyfert galaxy NGC 5728 reveals a spectacular bi-conical beam of light that is ionizing the gas in the central region of the galaxy.
