Hubble Finds That Dwarf Galaxies Formed More Than Their Fair Share of the Universe’s Stars

Hubble Finds That Dwarf Galaxies Formed More Than Their Fair Share of the Universe's Stars

They may be little, but they pack a big star-forming punch. New observations from NASA’s Hubble Space Telescope show that small galaxies, also known as dwarf galaxies, are responsible for forming a large proportion of the universe’s stars.

Studying this early epoch of the universe’s history is critical to fully understanding how these stars formed and how galaxies have grown and evolved 2 billion to 6 billion years after the beginning of the universe. This result supports a decade-long investigation into whether there is a link between a galaxy’s mass and its star-forming activity, and helps paint a consistent picture of events in the early universe.

“We already suspected these kinds of galaxies would contribute to the early wave of star formation, but this is the first time we’ve been able to measure the effect they actually had,” said Hakim Atek of the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, lead author of the study published in the June 19 online issue of The Astrophysical Journal. “They appear to have had a surprisingly huge role to play.”

Swiftly Moving Gas Streamer Eclipses Supermassive Black Hole

Swiftly Moving Gas Streamer Eclipses Supermassive Black Hole

An international team of astronomers using data from several NASA and European Space Agency (ESA) space observatories has discovered unexpected behavior from the supermassive black hole at the heart of the galaxy NGC 5548. Their findings may provide new insights into the interactions of supermassive black holes and their host galaxies.

Researchers detected a clumpy gas stream flowing rapidly outward from a supermassive black hole, blocking 90 percent of its emitted X-rays. This deep look into a black hole’s environment yields clues to the behavior of black holes embedded in the center of active galaxies.

“There are other galaxies that show gas streams near a black hole, but they haven’t changed their position as dramatically,” said Gerard Kriss of the Space Telescope Science Institute (STScI) in Baltimore, Maryland. “This is the first time we’ve seen a stream like this move into the line of sight. We just happened to get lucky.”

NASA’s Hubble to Begin Search Beyond Pluto for a New Horizons Mission Target

NASA's Hubble to Begin Search Beyond Pluto for a New Horizons Mission Target

After careful consideration and analysis, the Hubble Space Telescope Time Allocation Committee has recommended using Hubble to search for an object the Pluto-bound NASA New Horizons mission could visit after its flyby of Pluto in July 2015.

The planned search will involve targeting a small area of sky in search of a Kuiper Belt object (KBO) for the outbound spacecraft to visit. The Kuiper Belt is a vast debris field of icy bodies left over from the solar system’s formation 4.6 billion years ago. A KBO has never been seen up close because the belt is so far from the Sun, stretching out to a distance of 5 billion miles into a never-before-visited frontier of the solar system.

“I am pleased that our science peer-review process arrived at a consensus as to how to effectively use Hubble’s unique capabilities to support the science goals of the New Horizons mission,” said Matt Mountain, director of the Space Telescope Science Institute (STScI) in Baltimore, Maryland.
