A massive galaxy supercluster in the early universe

The structure of the universe is often described as being a cosmic web of filaments, nodes, and voids, with the nodes being clusters of galaxies, the largest gravitationally bound objects known. These nodes are thought to ...

Controlling the waveform of ultrashort infrared pulses

An international team of laser physicists of the attoworld team at LMU and the Max Planck Institute of Quantum Optics has achieved unprecedented control over light pulses in the mid-infrared wavelength range.

Astronomy team finds evidence of galactic metal shrouded in dust

A thorough understanding of galaxy evolution depends in part on an accurate measurement of the abundance of metals in the intergalactic medium—the space between stars—but dust can impede observations in optical wavelengths. ...

Scientists explain why Uranus and Neptune are different colors

Observations from Hubble Space Telescope, the NASA Infrared Telescope and the Gemini Observatory, reveal that excess haze on Uranus makes it paler than Neptune and that dark spots are caused by a darkening of a second deeper ...

New imaging spectrometer surveys atmospheric dust from the ISS

Scientists on Earth will soon see our planet's atmospheric dust sources in high resolution, as a new state-of-the-art imaging spectrometer—developed by NASA's Jet Propulsion Laboratory (JPL) and Cornell University—aims ...

The Milky Way's middle-aged inner ring

Using a combination of observed stars and a realistic model of the Milky Way, scientists at the Max Planck Institute for Extraterrestrial Physics have found a new structure in our home galaxy. Just outside the galactic bar, ...

NASA finalizes plans for its next cosmic mapmaker

NASA's upcoming SPHEREx mission will have some similarities with the James Webb Space Telescope. But the two observatories will take dramatically different approaches to studying the sky.
