Deep Space:



Planck Mission Brings Universe Into Sharp Focus

-> Planck's Universe

The Planck space mission has released the most accurate and detailed map ever made of the oldest light in the universe, revealing new information about its age, contents and origins.

Planck is a European Space Agency mission. NASA contributed mission-enabling technology for both of Planck's science instruments, and U.S., European and Canadian scientists work together to analyze the Planck data.

The map results suggest the universe is expanding more slowly than scientists thought, and is 13.8 billion years old, 100 million years older than previous estimates. The data also show there is less dark energy and more matter, both normal and dark matter, in the universe than previously known. Dark matter is an invisible substance that can only be seen through the effects of its gravity, while dark energy is pushing our universe apart. The nature of both remains mysterious.



The Cosmic Microwave Background - The Inflationary Universe

-> Cosmic  Microwave Background

The Cosmic Microwave Background, accidentaly detected in 1964 by Arno Penzias and Robert Wilson, is widely believed to be the radiation remnant of the Big Bang; The origin of the Universe.

In the images, the blue and red spots correspond to regions of greater or lesser density in the early Universe, 300,000 years after the Big Bang itself. These relics record the distribution of matter and energy in the early Universe before the matter became organized into stars and galaxies.

COBE's Infrared View Of The Universe

-> Infrared Universe

Astronomers have assembled the first definitive detection of a background infrared glow across the sky produced by dust warmed by all the stars that have existed since the beginning of time.

The discovery reveals a surprisingly large amount of starlight in the universe cannot be seen directly by today's optical telescopes, perhaps due to stars being hidden in dust, or being too faint or far away to be seen.


NASA Great Observatories Find Candidate for Most Distant Galaxy Yet Known

-> Most Distant Galaxy Yet Known

By combining the power of NASA's Hubble Space Telescope, Spitzer Space Telescope, and one of nature's own natural "zoom lenses" in space, astronomers have set a new distance record for finding the farthest galaxy yet seen in the universe.


NASA's Hubble Finds Most Distant Galaxy Candidate Ever Seen in Universe

-> Most Distant Galaxy

Astronomers have pushed NASA's Hubble Space Telescope to its limits by finding what is likely to be the most distant object ever seen in the universe. The object's light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder.


The Most Distant Galaxy in the Universe

-> Gravitational Lens

A Hubble Space Telescope image of the galaxy cluster CL1358+62 has uncovered a gravitationally-lensed image of a more distant galaxy located far beyond the cluster.

Hubble Finds Evidence for Dark Energy in the Young Universe

-> Dark Energy

Astronomers used the supernovae to measure the expansion rate of the universe and determine how the expansion rate is affected by the repulsive push of dark energy, a mysterious energy force that pervades space.


Blast from the Past: Farthest Supernova Ever Seen Sheds Light on Dark Universe

-> Deep Space Supernova

Gazing to the far reaches of space and time, NASA's Hubble Space Telescope identified the farthest stellar explosion ever seen, a supernova that erupted 10 billion years ago. By examining the glow from this dying star, astronomers have amassed more evidence that a mysterious, repulsive force is at work in the cosmos, making galaxies rush ever faster away from each other.


Hubble Finds Ring of Dark Matter

-> Ring of Dark Matter

Astronomers using NASA's Hubble Space Telescope have discovered a ghostly ring of dark matter that formed long ago during a titanic collision between two massive galaxy clusters. The ring's discovery is among the strongest evidence yet that dark matter exists.


Detailed Dark Matter Map Yields Clues to Galaxy Cluster Growth

-> Dark Matter Map in Abell 1689

Astronomers using NASA's Hubble Space Telescope received a boost from a cosmic magnifying glass to construct one of the sharpest maps of dark matter in the universe.


Hubble's Largest Galaxy Portrait Offers a New High-Definition View of M101

-> M101 - Pinwheel Galaxy

Hubble Space Telescope image of the face-on spiral galaxy Messier 101 (M101). It is the largest and most detailed photo of a spiral galaxy that has ever been released from Hubble. The galaxy's portrait is actually composed of 51 individual Hubble exposures, in addition to elements from images from ground-based photos. The final composite image measures a whopping 16,000 by 12,000 pixels.


Hubble Photographs Grand Design Spiral Galaxy M81

-> M81 - Bode's Galaxy

The sharpest image ever taken of the large "grand design" spiral galaxy M81 was released today at the American Astronomical Society Meeting in Honolulu, Hawaii. A spiral-shaped system of stars, dust, and gas clouds, the galaxy's arms wind all the way down into the nucleus.


Hubble Observes Infant Stars in Nearby Galaxy

-> Infant Stars

This new image taken with NASA's Hubble Space Telescope depicts bright, blue, newly formed stars that are blowing a cavity in the center of a star-forming region in the Small Magellanic Cloud.


Dark, but Light: Smallest Galaxies Ever Seen Solve a Big Problem

-> Dwarf galaxies orbiting the Milky Way

Mauna Kea scientists may have solved a discrepancy between the number of extremely small, faint galaxies predicted to exist near the Milky Way and the number actually observed.
In an attempt to resolve the "Missing Dwarf Galaxy" problem, two astronomers used the W. M. Keck Observatory to study a population of the darkest, most lightweight galaxies known, each containing 99% dark matter.


Our Galaxy, The Milky Way:



Lone Black Holes Discovered Adrift in the Galaxy

-> Black Holes Adrift in the Galaxy

Two images of a crowded starfield as seen through a ground-based telescope show the subtle brightening of a star due to the effect of gravitational microlensing, where an invisible but massive foreground object passes in front of the star and amplifies its light. The dark lensing object is estimated to be a six-solar-mass black hole that is drifting alone among the stars.


Hubble Images a Swarm of Ancient Stars

-> M80 - Globular Cluster

This stellar swarm is M80 (NGC 6093), one of the densest of the 147 known globular star clusters in the Milky Way galaxy. Located about 28,000 light-years from Earth, M80 contains hundreds of thousands of stars, all held together by their mutual gravitational attraction.

The image celebrates the 20th anniversary of Hubble's launch and deployment into an orbit around Earth.


Embryonic stars emerge from Evaporating Gaseous Globules "EGGs"

-> Embryonic Stars in the Eagle Nebula

Dramatic pictures from NASA's Hubble Space Telescope, show newborn stars emerging from dense, compact pockets of interstellar gas called Evaporating Gaseous Globules (EGGs).
Hubble found the "EGGs", appropriately enough, in the Eagle nebula, a nearby star-forming region 7,000 light-years away in the constellation Serpens.


A Giant Hubble Mosaic of the Crab Nebula

-> M1 - Crab Nebula

The Crab Nebula (M1, NGC 1952) is a six-light-year-wide expanding remnant of a star's supernova explosion. Japanese and Chinese astronomers recorded this violent event nearly 1,000 years ago in 1054, as did, almost certainly, Native Americans. This composite image was assembled from 24 individual exposures taken with the NASA Hubble Space Telescope's Wide Field and Planetary Camera 2 in October 1999, January 2000, and December 2000. It is one of the largest images taken by Hubble and is the highest resolution image ever made of the entire Crab Nebula.


The Orion Nebula

Update: Hubble Panoramic View of Orion Nebula Reveals Thousands of Stars (January '06)

-> M42 - Orion Nebula

Located 1,500 light-years away, along our spiral arm of the Milky Way, the Orion nebula is located in the middle of the Sword region of the constellation Orion the Hunter, which dominates the early winter evening sky, at northern latitudes. The stars have formed from collapsing clouds of interstellar gas within the last million years. The most massive clouds have formed the brightest stars near the center and these are so hot that they illuminate the gas left behind after the period of star formation was complete.

Hubble Views the Pluto System

-> Hubble - Pluto System

These Hubble Space Telescope images reveal Pluto, its large moon Charon, and the planet's two new candidate satellites. Between May 15 and May 18, 2005, Charon, and the putative moons all appear to rotate counterclockwise around Pluto.

The candidate moons, provisionally designated S/2005 P1 and S/2005 P2, were observed to be approximately 27,000 miles (44,000 kilometers) away from Pluto. The objects are roughly two to three times as far from Pluto as Charon.


New Hubble Maps of Pluto Show Surface Changes

-> Hubble - Maps of Pluto

NASA's Hubble Space Telescope has now mapped the dwarf planet in never-before-seen detail.

The new map is so good, astronomers have even been able to detect changes on the dwarf planet's surface by comparing Hubble images taken in 1994 with the newer images taken in 2002-2003.


Hubble Makes Movie of Neptune's Dynamic Atmosphere

-> Hubble - Neptune's Atmosphere

NASA's Hubble Space Telescope captures the distant blue-green world, Neptune, and its satellites in this portrait. Astronomers used Hubble's assortment of filters to pinpoint high altitude clouds floating above the methane rich atmosphere. The icy moons seen in this view are Proteus (the brightest), Larissa, Despina, and Galatea. Neptune had 13 moons at last count. In Roman mythology, Larsissa and Despina were Neptunes's daughters.

The Hubble Space Telescope (HST)

-> Hubble Space Telescope

Just as Galileo's first use of a telescope to see the sky [in 1609] gave humanity its first order-of-magnitude increase in resolution for this kind of vision, the HST gave us the second one. The unaided eye can resolve nearly 1' of arc, a ground-based telescope near 1", the HST resolves 0.1" of arc.


In October 31 '06 NASA announced that it would go ahead with one final space shuttle mission to repair and upgrade Hubble after months of debate over the risks of such an endeavor.
The decision was taken by NASA's chief Michael Griffin, who had said for 18 months that he would support a proposed Hubble servicing mission provided its risk did not exceed that already accepted for other shuttle flights. The Service Mission 4 will add 5 years onto the Hubble's lifetime and could help NASA prepare the space telescope for its ultimate, but controlled, plunge through the Earth's atmosphere.
Griffin said the upcoming servicing mission would launch in 2008 between construction flights to complete the International Space Station (ISS), and was expected to feature at least five spacewalks to upgrade Hubble's optics and make other repairs.
For safety, NASA would have a second shuttle nearly ready to fly before staging the servicing flight.
Service Mission 4 (SM4) was delayed for May 12, 2009 and successfuly completed.
