A new instrument concept, ngRADAR, will use the Green Bank Telescope and other facilities to expand on ground-based radar capabilities. The system has the potential to increase resolution imaging and characterize hazardous objects in unprecedented detail.
For the first time, astronomers have imaged a black hole's shadow along with its powerful jet. The new image reveals more details about the location and energy of highly energetic electrons and magnetic fields. Scientists also discovered that the black hole is not very hungry, consuming matter at a low rate.
The Green Bank Telescope's new radar system produced highest resolution images of the Moon ever captured from Earth, paving the way for a next-generation radar system to study planets, moons, and asteroids. The flagship system will serve in planetary defense, detecting and tracking potentially hazardous objects.
A team of astronomers used the Green Bank Telescope to image a galaxy cluster and revealed new information about a supermassive black hole. The study found that at least a portion of the pressure support in the cavities is due to non-thermal sources, such as relativistic particles and cosmic rays.
Astronomers using the Green Bank Telescope have discovered a millisecond pulsar with a massive neutron star at its center, packing 2.17 times the mass of our Sun into a sphere only 30 kilometers across. This finding approaches the limits of how massive and compact an object can become without crushing itself down into a black hole.
An international team of astronomers tested the Strong Equivalence Principle using a unique triple star system. They found that even extremely dense neutron stars fall at the same rate as lighter objects, confirming Einstein's general theory of relativity.
Astronomers identify hydrogenated nanodiamonds as likely source of anomalous microwave emission (AME), a type of faint microwave light emanating from regions across the Milky Way. The discovery provides new insights into the formation of nanodiamonds in protoplanetary disks and has implications for cosmology research.
