Emission Spectrum from Blazar PKS 1424+240 Deviates from Expectations

Distant Blazar Emission Spectrum Deviates from Expectations

Using data from the Hubble Space Telescope, researchers noticed that the emission spectrum from blazar PKS 1424+240 deviated from what was expected, possibly indicating something new about the emission mechanisms of blazars, the extragalactic background light, or the propagation of gamma-ray photons over long distances. Blazars are the brightest of active galactic nuclei, and many […]

Changes to Algorithm Improve Analysis of the Evolution of Quasars

The Most Rigorous Analysis Yet of the Evolution of Quasars

By improving an algorithm that is important for studying quasars, astrophysicists determined the radio and optical luminosity evolutions for a set of more than 5000 quasars combining SDSS optical and FIRST radio data. In the nearly six decades since quasars were discovered, the list of these energetic galaxies powered by supermassive black holes has grown […]

Astronomers Discover Earliest Starburst Galaxy Ever Observed

Starburst Galaxy HFLS3

A large team of astronomers has discovered the earliest starburst galaxy ever observed. Occurring just 880 million years after the Big Bang, HFLS3 is a dust-filled, massive galaxy generating the mass equivalent of 2,900 suns per year. Pasadena, California — Smaller begets bigger. Such is often the case for galaxies, at least: the first galaxies […]

New Solar Structure Cools Buildings in Full Sunlight

New Form of Cooling Panel Works Even When the Sun is Shining

Scientists at Stanford University have designed an entirely new form of cooling structure that cools when the sun is shining by reflecting sunlight and emitting thermal radiation within the crucial wavelength range needed to escape Earth’s atmosphere. Homes and buildings chilled without air conditioners. Car interiors that don’t heat up in the summer sun. Tapping […]

How to Target and Collide With a Potentially Hazardous Asteroid

How to Target and Collide with an Asteroid

While some NASA scientists work to capture and explore an asteroid, other NASA scientists are calculating how to target and collide with an asteroid, running hypervelocity impact simulations that could one day change a potentially hazardous asteroid’s orbit. Like many of his colleagues at NASA’s Jet Propulsion Laboratory, Pasadena, California, Shyam Bhaskaran is working a […]
