NASA will reveal new findings about black holes during a news conference Wednesday (Feb. 27).

The news conference, which starts at 1 p.m. EST (1800 GMT) Wednesday, will relay results based primarily on observations made by two X-ray space telescopes: NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Space Agency’s XMM-Newton observatory, NASA officials said.

The scientists participating in the briefing are:

  • Fiona Harrison, NuSTAR principal investigator at Caltech in Pasadena
  • Guido Risaliti, astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass.
  • Arvind Parmar, head of Astrophysics and Fundamental Physics Missions Division, European Space Agency

NASA will stream audio of the teleconference, along with participants' visual aids, live at will carry the NASA feed here.

The $165 million NuSTAR observatory launched in June 2012, kicking off a planned two-year mission to study the universe in high-energy X-ray light. The telescope's observations should help scientists better understand galaxy formation, black hole growth and other phenomena, mission team members have said.

XMM-Newton is a grizzled space veteran by comparison. The telescope launched in December 1999 and has been probing X-ray emissions around the universe ever since.
