Mystery of Galaxy's Missing Dark Matter Deepens
June 17, 2021, 6:55 a.m.Read more
When astronomers using NASA’s Hubble Space Telescope uncovered an oddball galaxy that looks like it doesn’t have much dark matter, some thought the finding was hard to believe and looked for a simpler explanation. Dark matter, after all, is the invisible glue that makes up the bulk of the universe’s contents. All galaxies are dominated by it; in fact, galaxies are thought to form inside immense halos of dark matter. So, finding a galaxy lacking the invisible stuff is an extraordinary claim that challenges conventional wisdom. It would have the potential to upset theories of galaxy formation and evolution.For more information, visit https://nasa.gov/hubble. Additional Visualizations:Galaxy Motion Simulation: Credit: ESO/L.

Hubble Makes Unexpected Dark Matter Discovery

Astronomers seem to have revealed a puzzling detail in the way dark matter behaves. They found small, dense concentrations of dark matter that bend and magnify light much more strongly than expected.For more information, visit https://nasa.gov/hubble.Visualizations and Additional Footage:ESA/Hubble — Gravitational Lensing AnimationESA/Hubble — Gravitational Lensing Simplified VisualizationR.

Star Gives Birth to Possible Black Hole in Hubble and Spitzer Images

A team of astronomers at The Ohio State University watched a star disappear and possibly become a black hole. Instead of becoming a black hole through the expected process of a supernova, the black hole candidate formed through a Killer Tracks Production MusicWatch this video on the NASA Goddard YouTube channel.

Planck data reveals that the universe , that acts as a sort of an anti-gravity. This energy, distinct from dark matter, is responsible for the present-day acceleration of the universal expansion.

NASA's Fermi Mission Broadens its Dark Matter Search
Aug. 12, 2016, 9 a.m.Read more
Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, the results are helping scientists rule out some of the many theoretical possibilities. Three studies published earlier this year, using six or more years of data from NASA s Fermi Mission Expands its Search for Dark Matter](http://www.nasa.gov/feature/goddard/2016/nasas-fermi-mission-expands-its-search-for-dark-matter)
Turning Black Holes into Dark Matter Labs
June 23, 2015, 10 a.m.Read more
A new computer simulation tracking dark matter particles in the extreme gravity of a black hole shows that strong, potentially observable gamma-ray light can be produced. Detecting this emission would provide astronomers with a new tool for understanding both black holes and the nature of dark matter, an elusive substance accounting for most of the mass of the universe that neither reflects, absorbs nor emits light. Jeremy Schnittman, an astrophysicist at NASA s equator and event horizon. The gamma rays with the greatest chances of escape are produced on the side of the black hole that spins toward us. Such lopsided emission is typical for a rotating black hole.Credit: NASA Goddard/Jeremy Schnittman Same as above but aligned with the visualization image below.Credit: NASA Goddard/Jeremy Schnittman A single frame of the visulization previously described.

WIMPs—Weakly Interacting Massive Particles

Weakly Interacting Massive Particles, or WIMPs, represent one hypothesized class of particles to explain dark matter.They neither absorb nor emit light and don t interact strongly with other particles. But when they encounter each other, they annihilate and make gamma rays.

Missing Dark Matter

A bizarre, ghostly galaxy lacks dark matter. Learn more about dark matter and why the discovery of galaxy NGC 1052-DF2 puzzled astronomers. The ghostly galaxy NGC 1052-DF2 is about 62 million light-years away from Earth and about 10 billion years old. Using the speed of 10 bright star clusters, researchers calculated the galaxy s mass, which is entirely accounted for by visible stars.
