Baltimore, MD – Astronomers using NASA’s Hubble Space Telescope have discovered that the universe is expanding 5 percent to 9 percent faster than expected.

“This surprising finding may be an important clue to understanding those mysterious parts of the universe that make up 95 percent of everything and don’t emit light, such as dark energy, dark matter and dark radiation,” said study leader and Nobel Laureate Adam Riess of the Space Telescope Science Institute and Johns Hopkins University, both in Baltimore, Maryland.

NASA reports Planck Space Telescope helps Scientists look at the Universe’s Past

Pasadena, CA – Hot gas, dust and magnetic fields mingle in a colorful swirl in this new map of our Milky Way galaxy. The image is part of a new and improved data set from Planck, a European Space Agency mission in which NASA played a key role.

Planck spent more than four years observing relic radiation left over from the birth of our universe, called the cosmic microwave background. The space telescope is helping scientists better understand the history and fabric of our universe, as well as our own Milky Way.

A festive portrait of our Milky Way galaxy shows a mishmash of gas, charged particles and several types of dust. The composite image comes from the European Space Agency’s Planck mission, in which NASA plays an important role. It is constructed from observations made at microwave and millimeter wavelengths of light, which are longer than what we see with our eyes.

Pasadena, CA – A new image from the Planck space telescope reveals the magnetic field lines of our Milky Way galaxy. The fingerprint-like map allows astronomers to study the structure of the magnetic field and better understand the process of star formation.

The image, compiled from the first all-sky observations of polarized light emitted by interstellar dust in the Milky Way, is available here.

NASA reports Planck Space Telescope switched off after 4.5 years of service

Pasadena, CA – The Planck space telescope has been turned off after spending nearly 4.5 years soaking up the relic radiation from the Big Bang and studying the evolution of stars and galaxies throughout the history of the universe.

Planck is a European Space Agency (ESA) mission with significant contributions from NASA.

Mission controllers at ESA’s operations center in Darmstadt, Germany sent the final command to the Planck satellite today, marking the end of operations for what some like to call a “time machine.”

The oldest light in the universe, called the cosmic microwave background, as observed by the Planck space telescope is shown in the oval sky map. An artist’s concept of Planck is next to the map. (ESA and the Planck Collaboration – D. Ducros)

NASA’s Planck Space Telescope discovers pair of Galaxies connected by Bridge of Hot Gas

Pasadena, CA – The Planck space telescope has made the first conclusive detection of a bridge of hot gas connecting a pair of galaxy clusters across 10 million light-years of intergalactic space.

“Planck is helping to reveal hidden material between galaxy clusters that we couldn’t see clearly before,” said James Bartlett of NASA’s Jet Propulsion Laboratory, Pasadena, CA, a member of the U.S. Planck science team. Planck is a European Space Agency mission with significant participation from NASA.

Planck has discovered a bridge of hot gas that connects galaxy clusters Abell 399 (lower center) and Abell 401 (top left). The galaxy pair is located about a billion light-years from Earth, and the gas bridge extends approximately 10 million light-years between them.
