NASA uses Pulsars to detect Gravitational Waves

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space.

So far, there have been five detections of gravitational waves, thanks to the Laser Interferometer Gravitational-Wave Observatory (LIGO) and, more recently, the European Virgo gravitational-wave detector. Using these facilities, scientists have been able to pin down the extremely subtle signals from relatively small black holes and, as of October, neutron stars.

This computer simulation shows the collision of two black holes, which produces gravitational waves. (SXS)

NASA prepares for future Satellite by studying Coral Reefs of Hawaii

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA pulled off a scientific double play in Hawaii this winter, using the same instruments and aircraft to study both volcanoes and coral reefs. Besides helping scientists understand these two unique environments better, the data will be used to evaluate the possibility of preparing a potential future NASA satellite that would monitor ecosystem changes and natural hazards.

The advantages of studying active volcanoes from the air rather than the ground are obvious. Coral reefs may not offer the same risks in a close encounter that volcanoes do, but there’s another good reason to study them by remote sensing: they’re dotted across thousands of square miles of the globe.

NASA’s Spitzer Space Telescope takes infrared image of The Spider Nebula

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A nebula known as “the Spider” glows fluorescent green in an infrared image from NASA’s Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS).

The Spider, officially named IC 417, lies near a much smaller object called NGC 1931, not pictured in the image. Together, the two are called “The Spider and the Fly” nebulae. Nebulae are clouds of interstellar gas and dust where stars can form.

The Spider Nebula lies about 10,000 light-years away from Earth and is a site of active star formation. (NASA/JPL-Caltech/2MASS)

NASA’s Hubble Telescope Confirms that Galaxies are the Ultimate Recyclers

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – New observations by NASA’s Hubble Space Telescope are expanding astronomers’ understanding of the ways in which galaxies continuously recycle immense volumes of hydrogen gas and heavy elements. This process allows galaxies to build successive generations of stars stretching over billions of years.

This ongoing recycling keeps some galaxies from emptying their “fuel tanks” and stretches their star-forming epoch to over 10 billion years.

This conclusion is based on a series of Hubble Space Telescope observations that flexed the special capabilities of its Cosmic Origins Spectrograph (COS) to detect gas in the halo of our Milky Way and more than 40 other galaxies. Data from large ground-based telescopes in Hawaii, Arizona and Chile also contributed to the studies by measuring the properties of the galaxies.

Distant quasars shine through the gas-rich "fog" of hot plasma encircling galaxies. At ultraviolet wavelengths, Hubble's Cosmic Origins Spectrograph (COS) is sensitive to absorption from many ionized heavy elements, such as nitrogen, oxygen, and neon. COS's high sensitivity allows many galaxies that happen to lie in front of the much more distant quasars. (Credit: NASA; ESA; A. Feild, STScI)
