Space Telescope Science Institute Astrophysicist Elected to National Academy of Sciences

Adam Riess was among 72 scientists elected today to membership in the National Academy of Sciences at the organization’s 146th annual meeting, held in Washington, D.C.

Riess, an astronomer at the Space Telescope Science Institute (STScI) and professor in the Henry A. Rowland Department of Physics and Astronomy in the Zanvyl Krieger School of Arts and Sciences, joins 20 other Johns Hopkins faculty members currently in the Academy, an honorary society that advises the government on scientific matters.

Astronomers Spy Oldest Object in Universe Yet

Astronomers have spotted a burst of energy from a dying star, setting a record for the oldest and most distant object seen by Earth yet.

Astronomers Spy Oldest Object in Universe Yet

The 10-second blast was from more than 13 billion years ago, when the universe was only 630 million years old.

NASA’s Swift satellite spotted the gamma-ray burst, an explosion of high-powered radiation, on April 23. Then ground telescopes watched the afterglow and calculated it had traveled about 13.1 billion light years to get here. It beat old records by 100 or 200 hundred million light years.

Galaxy Cluster MACS J0717

April 16, 2009: The most crowded collision of galaxy clusters has been identified by combining
information from three different telescopes. This result gives scientists a chance
to learn what happens when some of the largest objects in the universe go at each
other in a cosmic free-for-all. Using data from NASA’s Chandra X-ray Observatory,
Hubble Space Telescope, and the Keck Observatory in Hawaii, astronomers were
able to determine the three-dimensional geometry and motion in the system
MACS J0717.5+3745 (or MACS J0717, for short), located about 5.4 billion light-years
from Earth.

Hubble Witnesses Spectacular Flaring in Gas Jet from M87’s Black Hole

A flare-up in a jet of matter blasting from a monster black hole is giving astronomers an incredible light show.

Hubble Witnesses Spectacular Flaring in Gas Jet from M87's Black Hole

The outburst is coming from a blob of matter, called HST-1, embedded in the jet, a powerful narrow beam of hot gas produced by a supermassive black hole residing in the core of the giant elliptical galaxy M87. HST-1 is so bright that it is outshining even M87’s brilliant core, whose monster black hole is one of the most massive yet discovered.

The glowing gas clump has taken astronomers on a rollercoaster ride of suspense. Astronomers watched HST-1 brighten steadily for several years, then fade, and then brighten again. They say it’s hard to predict what will happen next.

Hubble Finds Hidden Exoplanet in Archival Data

A powerful, newly refined image-processing technique may allow astronomers to discover extrasolar planets that are possibly lurking in over a decade’s worth of Hubble Space Telescope archival data.

Hubble Finds Hidden Exoplanet in Archival Data

David Lafreniere of the University of Toronto, Ontario, Canada, has successfully demonstrated this new strategy for planet hunting by identifying an exoplanet that went undetected in Hubble images taken in 1998 with its Near Infrared Camera and Multi-Object Spectrometer (NICMOS). In addition to illustrating the power of new data-processing techniques, this finding underscores the value of the Hubble data archive, on which those new techniques can be used.
