NASA’s Spitzer, Hubble and Herschel Space Telescopes observes Warm Gases stopping Galaxy from making new Stars

NASA - National Aeronautics and Space AdministrationPasadena, CA – Some like it hot, but for creating new stars, a cool cosmic environment is ideal. As a new study suggests, a surge of warm gas into a nearby galaxy — left over from the devouring of a separate galaxy — has extinguished star formation by agitating the available chilled gas.

The unique findings illustrate a new dimension to galaxy evolution, and come courtesy of the European Space Agency’s Herschel space observatory, in which NASA played a key role, and NASA’s Spitzer and Hubble space telescopes.

NASA researchers discover dusty star system similar to our solar system

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers studying what appears to be a beefed-up version of our solar system have discovered that it is encased in a halo of fine dust. The findings are based on infrared data from NASA’s Spitzer Space Telescope and the European Space Agency’s Herschel Space Observatory, in which NASA is a partner.

The dusty star system, called HD 95086, is located 295 light-years from Earth in the constellation Carina. It is thought to include two belts of dust, which lie within the newfound outer dust halo.

This artist's concept depicts giant planets circling between belts of dust. Scientists think the star system HD 95068 may have a planetary architecture similar to this. While the star system's two dust belts are known, along with one massive planet, more giant planets may lurk unseen. (NASA/JPL-Caltech)

NASA Telescopes reveal Giant Galaxy in the early stages of creation

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed “Sparky,” is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate.

The discovery was made possible through combined observations from NASA’s Hubble and Spitzer space telescopes, the W.M. Keck Observatory in Mauna Kea, Hawaii, and the European Space Agency’s Herschel space observatory, in which NASA plays an important role.

NASA observes Fireworks created by Black Hole in Nearby Galaxy

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Celebrants this Fourth of July will enjoy the dazzling lights and booming shock waves from the explosions of fireworks. A similarly styled event is taking place in the galaxy Messier 106, as seen by NASA’s Spitzer Space Telescope, Chandra X-ray Observatory and the Herschel Space Observatory. Herschel is a European Space Agency mission with important NASA contributions.

Energetic jets, which blast from Messier 106’s central black hole, are heating up material in the galaxy and thus making it glow, like the ingredients in a firework. The jets also power shock waves that are driving gases out of the galaxy’s interior.

A galaxy about 23 million light-years away is the site of impressive, ongoing, fireworks. Rather than paper, powder, and fire, this galactic light show involves a giant black hole, shock waves, and vast reservoirs of gas. (NASA/CXC/JPL-Caltech/STScI/NSF/NRAO/VLA)

NASA says Herschel Space Observatory has discovered Giant Weird Ring Structure along with growing Stars

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Herschel Space Observatory has uncovered a weird ring of dusty material while obtaining one of the sharpest scans to date of a huge cloud of gas and dust, called NGC 7538.

The observations have revealed numerous clumps of material, a baker’s dozen of which may evolve into the most powerful kinds of stars in the universe. Herschel is a European Space Agency mission with important NASA contributions.

NASA says Herschel Space Observatory has found Young Galaxy acting mature for it’s age

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists have discovered a young galaxy acting in unexpectedly mature ways. The galaxy, called S0901, is rotating in a calm manner typical of more developed galaxies like our own spiral Milky Way.

“Usually, when astronomers examine galaxies in an early era, they find that turbulence plays a much greater role than it does in modern galaxies. But S0901 is a clear exception to that pattern,” said James Rhoads of Arizona State University, Tempe.

The young galaxy SDSS090122.37+181432.3, also known as S0901, is seen here as the bright arc to the left of the central bright galaxy. (NASA/STScI; S. Allam and team; and the Master Lens Database, L. A. Moustakas, K. Stewart, et al (2014))

NASA astronomers to use Hubble, Spitzer, Herschel space telescopes to examine Burned Out Elliptical Galaxies

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers using NASA’s Hubble and Spitzer space telescopes, and Europe’s Herschel Space Observatory, have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in the history of the universe.

Enabled by Hubble’s infrared imaging capabilities, astronomers have assembled for the first time a representative spectroscopic sampling of ultra-compact, burned-out elliptical galaxies — galaxies whose star formation was finished when the universe was only 3 billion years old, less than a quarter of its current estimated age of 13.8 billion years.

This graphic shows the evolutionary sequence in the growth of massive elliptical galaxies over 13 billion years, as gleaned from space-based and ground-based telescopic observations. The growth of this class of galaxies is quickly driven by rapid star formation and mergers with other galaxies. Image Credit: NASA, ESA, S. Toft (Niels Bohr Institute), and A. Feild (STScI)

NASA reports Herschel Space Observatory discovers water vapor on Dwarf Planet Ceres

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Scientists using the Herschel space observatory have made the first definitive detection of water vapor on the largest and roundest object in the asteroid belt, dwarf planet Ceres.

“This is the first time water vapor has been unequivocally detected on Ceres or any other object in the asteroid belt and provides proof that Ceres has an icy surface and an atmosphere,” said Michael Küppers of ESA in Spain, lead author of a paper in the journal Nature.

NASA’s Spitzer Space Telescope studies cluster galaxies

 

Written by Whitney Clavin

NASA - National Aeronautics and Space AdministrationPasadena, CA – In the fable of the town and country mice, the country mouse visits his city-dwelling cousin to discover a world of opulence. In the early cosmos, billions of years ago, galaxies resided in the equivalent of urban or country environments.

Those that dwelled in crowded areas called clusters also experienced a kind of opulence, with lots of cold gas, or fuel, for making stars.

Today, however, these galactic metropolises are ghost towns, populated by galaxies that can no longer form stars. How did they get this way and when did the fall of galactic cities occur?

The collection of red dots seen near the center of this image show one of several very distant galaxy clusters discovered by combining ground-based optical data from the National Optical Astronomy Observatory's Kitt Peak National Observatory with infrared data from NASA's Spitzer Space Telescope. This galaxy cluster, named ISCS J1434.7+3519, is located about 9 billion light-years from Earth. (NASA/JPL-Caltech/KPNO/University of Missouri-Kansas City)

NASA’s says Herschel Space Observatory has discovered Argon gas pairing in Crab Nebula

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers have discovered a rare chemical pairing in the remains of an exploded star, called the Crab nebula. A gas thought to be a loner has made a “friend,” linking up with a chemical partner to form a molecule.

The discovery, made with the Herschel space observatory, a European Space Agency mission with important NASA contributions, will help scientists better understand supernovas, the violent deaths of massive stars.
