The Giant Magellan Telescope is a marvel of engineering, and Dr. Patrick McCarthy explains the years-long process to make an optic mirror that costs over $20 million. (more…)
Program Executive Office (PEO) Soldier’s new commanding officer Brigadier General Anthony Potts has gotten to grips with one of PEO Soldier’s most interesting projects, Textron’s Cased Telescoped Light Machine Gun. The Cased Telescoped...Show More Summary
A new Hubble finding confirms a nagging discrepancy showing the universe to be expanding faster now than was expected from its trajectory seen shortly after the big bang. Researchers suggest that there may be new physics to explain the inconsistency....
(NASA/Goddard Space Flight Center) Astronomers have used NASA's Hubble Space Telescope to make the most precise measurements of the expansion rate of the universe since it was first calculated nearly a century ago. Intriguingly, the results are forcing astronomers to consider that they may be seeing evidence of something unexpected at work in the universe.
(University of Central Florida) The largest fully operational radio telescope on the planet -- the Arecibo Observatory in Puerto Rico -- will soon be under new management. A consortium led by the University of Central Florida will start formal transition activities to take on the management of the National Science Foundation's Observatory. Show More Summary
Amateur astronomer Victor Buso was testing his camera-telescope setup in Argentina back in September 2016, pointing his Newtonian telescope at a spiral galaxy called NGC613. He collected light from the galaxy for the next hour and a half, taking short exposures to keep out the Santa Fe city lights. Show More Summary

A huge storm on Neptune is disappearing, and the Hubble Telescope is documenting it for the first time. The storm has led scientists to question their understanding of the prevailing dynamics of Neptune's atmosphere. The storm appears...Show More Summary
An intriguing feature of its orbit ties this telescope's destiny to a lunar schedule.
The planet Mars has fascinated scientists for over a century. Today, it is a frigid desert world with a carbon dioxide atmosphere 100 times thinner than Earth's. But evidence suggests that in the early history of our solar system, Mars had an ocean's worth of water. Show More Summary
(NASA/Goddard Space Flight Center) NASA's James Webb Space Telescope will study Mars to learn more about the planet's transition from wet to dry, and what that means about its past and present habitability.
An article in Science by Daniel Clery investigates the mystery of why half the astronomers who are granted telescope time never seem to publish their results: “‘Still working’: Astronomers explain why they don’t publish”. I’ve often compared anthropology to astronomy in terms of data sharing and data generation. Show More Summary
Thanks to data collected by NASA's Chandra X-ray telescope on galaxies up to 3.5 billion light years away from Earth, an international team of astrophysicists has detected what are likely to be the most massive black holes ever discovered in the universe. Show More Summary
The search for extraterrestrial life has shifted gears over the last five years or so, with the Kepler Space Telescope alone bringing thousands of potentially habitable Earth-sized planets into focus. Things are unlikely to slow down...Show More Summary
It seems nothing can escape the inexorable spread of light pollution—not even the giant telescopes probing the heavens above northern Chile, a region whose pristine dark skies, long considered a paradise for astronomers, are under increasing threat.
In 2015, the Hubble Space Telescope detected a strange feature in the skies over Neptune - a swirling dark vortex the size of China. Packing copious amounts of hydrogen sulfide - the chemical ingredient that gives farts their awful smell - this storm is not behaving as astronomers predicted, with the latest results suggesting the dark vortex is dying.

NASA's Kepler space telescope was launched for the purpose of finding new objects, like planets, far off in space, and it has done its job so incredibly well astronomers now have more new planets than they know what to do with. Researchers...Show More Summary
Kepler is the gift that keeps on giving. After suffering a major malfunction five years ago, the rejiggered space-based telescope continues to churn away, scanning the heavens for signs of distant worlds. An international team of astronomers has now released the results of its latest survey, confirming the existence of nearly 100 new exoplanets. More »
The Hubble Space Telescope has captured a stunningly detailed view of the weakly barred spiral galaxy NGC 3344, which is located some 20 million light-years away in the direction of the "Lion Cub" constellation, Leo Minor. NGC 3344 is...Show More Summary
