Monster black holes, neutron stars and pulsars are the targets of a new NASA space telescope mission scheduled to launch in 2020.
Black holes can heat up nearby gases, which, in turn, emit high-energy X-rays. NASA's new Imaging X-ray Polarimetry Explorer (IXPE) mission will use three space telescopes equipped with cameras to measure the polarization (direction of vibration) of these X-rays. The mission will cost about $188 million, NASA officials said.
"We cannot directly image what's going on near objects like black holes and neutron stars, but studying the polarization of X-rays emitted from their surrounding environments reveals the physics of these enigmatic objects, Paul Hertz, director of the Astrophysics Division of NASA's Science Mission Directorate, said in a statement from NASA.

The IXPE mission was selected for launch by NASA's Astrophysics Explorers program and will be led by Martin Weisskopf, principal investigator of NASA's Marshall Space Flight Center in Huntsville, Alabama.
The Italian Space Agency is helping to develop the cameras capable of measuring the powerful X-rays radiating from black holes. Ball Aerospace will provide the IXPE spacecraft and mission integration.
"NASA has a great history of launching observatories in the Astrophysics Explorers program with new and unique observational capabilities," Hertz said in the statement. "IXPE will open a new window on the universe for astronomers to peer through. Today, we can only guess what we will find."
