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

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

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.

Herschel Space Observatory discovers pools of Invisible Hydrogen Gas in the Milky Way Galaxy

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Newly formed stars shine brightly, practically crying out, “Hey, look at me!” But not everything in our Milky Way galaxy is easy to see. The bulk of material between the stars in the galaxy — the cool hydrogen gas from which stars spring — is nearly impossible to find.

A new study from the Herschel Space Observatory, a European Space Agency mission with important NASA participation, is shining a light on these hidden pools of gas, revealing their whereabouts and quantities. In the same way that dyes are used to visualize swirling motions of transparent fluids, the Herschel team has used a new tracer to map the invisible hydrogen gas.

NASA’s Herschel Space Observatory sees Two Galaxies Merge

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A massive and rare merging of two galaxies has been spotted in images taken by the Herschel space observatory, a European Space Agency mission with important NASA participation.

Follow-up studies by several telescopes on the ground and in space, including NASA’s Hubble Space Telescope and Spitzer Space Telescope, tell a tale of two faraway galaxies intertwined and furiously making stars. Eventually, the duo will settle down to form one super-giant elliptical galaxy.

NASA reports Herschel Space Observatory sees Hot Gases falling into Super Black Hole at center of Milky Way Galaxy

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Herschel space observatory has made detailed observations of surprisingly hot gas that may be orbiting or falling towards the supermassive black hole lurking at the center of our Milky Way galaxy. Herschel is a European Space Agency mission with important NASA participation.

“The black hole appears to be devouring the gas,” said Paul Goldsmith, the U.S. project scientist for Herschel at NASA’s Jet Propulsion Laboratory, Pasadena, CA. “This will teach us about how supermassive black holes grow.”

This artist's concept illustrates the frenzied activity at the core of our Milky Way galaxy. The galactic center hosts a supermassive black hole in the region known as Sagittarius A*, or Sgr A*, with a mass of about four million times that of our sun.

NASA reports Herschel Space Telescope completes mission

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Herschel observatory, a European space telescope for which NASA helped build instruments and process data, has stopped making observations after running out of liquid coolant as expected.

The European Space Agency mission, launched almost four years ago, revealed the universe’s “coolest” secrets by observing the frigid side of planet, star and galaxy formation.

NASA Astronomers using Herschel Space Observatory discover oldest star producing Galaxy to date

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers, including Matt Bradford, Jamie Bock, Darren Dowell, Hien Nguyen and Jonas Zmuidzinas of NASA’s Jet Propulsion Laboratory, Pasadena, CA, have discovered a dust-filled, massive galaxy churning out stars when the cosmos was a mere 880 million years old. This is the earliest starburst galaxy ever observed.

The discovery, appearing in the April 18th issue of Nature, was made using the European Space Agency’s Herschel space observatory, for which JPL helped build two instruments.

Herschel Space Observatory searches for Massive Stars

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In this new view of a vast star-forming cloud called W3, the Herschel space observatory tells the story of how massive stars are born. Herschel is a European Space Agency mission with important NASA contributions.

W3 is a giant gas cloud containing an enormous stellar nursery, some 6,200 light-years away in the Perseus Arm, one of our Milky Way galaxy’s main spiral arms.

W3 is an enormous stellar nursery about 6,200 light-years away in the Perseus Arm, one of the Milky Way galaxy's main spiral arms, which hosts both low- and high-mass star formation. In this image from the Herschel space observatory, the low-mass forming stars are seen as tiny yellow dots embedded in cool red filaments, while the highest-mass stars -- with greater than eight times the mass of our sun -- emit intense radiation, heating up the gas and dust around them and appearing here in blue.
