Simulations Uncover 'Flashy' Secrets of Merging Black Holes

09.27.2012
Scientists use simulations to investigate what kind of "flash" might be seen by telescopes when astronomers ultimately find gravitational signals from merging black holes.

NASA Pinning Down 'Here' Better Than Ever

02.23.2012
NASA is helping to lead an international effort to upgrade the four systems that supply crucial location information in pinpointing where "here" is.

Breakthrough Study Confirms Cause of Short Gamma-Ray Bursts

04.07.2011
A new supercomputer simulation shows the collision of two neutron stars can naturally produce the magnetic structures thought to power the high-speed particle jets associated with short gamma-ray bursts (GRBs).

Picometre precision demonstrated by LISA Pathfinder tests

10.22.2010
A European team working on the LISA Pathfinder mission has completed an extensive series of ground tests on the spacecraft's optical payload. The tests successfully achieved - for the first time on a spacecraft instrument - the incredible precision that will be required to confirm the existence of gravitational waves.

NASA'S Fermi Telescope Unveils a Dozen New Pulsars

01.06.2009
NASA's Fermi Gamma-ray Space Telescope has discovered 12 new gamma-ray-only pulsars and has detected gamma-ray pulses from 18 others. The finds are transforming our understanding of how these stellar cinders work.

Goddard Scientists Receive Lindsay Award for Black Hole Research

05.30.2008
Dr. Joan M. Centrella and Dr. John G. Baker are the 2008 recipients of the John C. Lindsay Memorial Award for Space Science. NASA's Goddard Space Flight Center in Greenbelt, Md., honors one or more of its civil servant space scientists each year with this award, which is the center's highest honor for outstanding contributions in space science.

NASA Scientists Predict Black Hole Light Echo Show

01.10.2008
It's well known that black holes can slow time to a crawl and tidally stretch large objects into spaghetti-like strands. But according to new theoretical research from two NASA astrophysicists, the wrenching gravity just outside the outer boundary of a black hole can produce yet another bizarre effect: light echoes.

NASA Scientists Pioneer Technique for "Weighing" Black Holes

05.16.2007
Two astrophysicists at NASA's Goddard Space Flight Center in Greenbelt, Md., Nikolai Shaposhnikov and Lev Titarchuk, have successfully tested a new method for determining the masses of black holes.

NASA Hosts Meeting for Scientists To Discuss Waves in Spacetime

06.14.2006
Gravitational waves promise to offer an entirely new window to observe the universe, a view based not on electromagnetic energy (radio, light, X-rays, gamma rays) but on gravitational energy.

NASA Achieves Breakthrough In Black Hole Simulation

04.18.2006
NASA scientists have reached a breakthrough in computer modeling that allows them to simulate what gravitational waves from merging black holes look like. The three-dimensional simulations, the largest astrophysical calculations ever performed on a NASA supercomputer, provide the foundation to explore the universe in an entirely new way.
