Twenty-five years ago, yesterday, on 24 April 1990, one of the most important missions in the annals of scientific discovery got underway, with the launch of NASA’s Hubble Space Telescope. As described in yesterday’s AmericaSpace history article, […]

Shedding New Light On the Solar System: Celebrating 25 Years of Hubble Science (Part 1)

A photograph of the Hubble Space Telescope. taken by the crew of the STS-109 mission, following the successful completion of the fourth Hubble servicing mission in 2002. The iconic orbiting observatory, which celebrates 25 years of successful operation this month, has completely revolutionised our view of the Cosmos. Image Credit: NASA/STScI

Thunderstorms are a powerful force of nature, but the ones we experience on Earth are dwarfed by the ones on the gas giant planet Saturn. They are huge and can be larger […]

Stellar (and Planetary) Formation Near Milky Way's Supermassive Black Hole Possible, New Study Suggests

An artist’s illustration of the vicinity of the supermassive black hole in the center of the Milky Way galaxy, known as Sagittarius A* . Astronomers have discovered a population of more than 150 massive young stars (shown as blue dots) in recent years that orbit within 2 light-years from the black hole. Newer observational […]

Orbiting Rainbows: Using 'Glitter Clouds' to Search For and Image Exoplanets

The search for exoplanets may one day get a lot more glittery. It sounds a bit like science fiction, but a new NASA proposal called Orbiting Rainbows would use glitter-like materials to help image some of those far-away worlds, which could enable high-resolution imaging at a fraction of the cost.

Spitzer Space Telescope Discovers Distant Exoplanet Across the Milky Way

Utilising NASA’s Spitzer Space Telescope, astronomers have discovered a distant exoplanet located 13,000 light-years away, through gravitational microlensing. The red cone in the map above our Solar System, depicts the extend in the galaxy of the thousands of known exoplanets that have been discovered by NASA’s Kepler space telescope, while the red circle represents […]

Astronomers Detect Complex Organics Around Nearby Young Star; Produce Them in Simulated Conditions in the Lab

Artist’s impression of the protoplanetary disk surrounding the young star MWC 480. Astronomers using the Atacama Large Millimeter/submillimeter Array, or ALMA, have detected the complex organic molecule methyl cyanide in the outer reaches of the star’s protoplanetary disk, where comets are believed to form. This discovery suggests that complex organic chemistry and potentially the […]

New Study Finds Unusual Mathematical Pattern in Cosmic Radio Bursts

A dramatic night-time image of the 64-m Parkes radio telescope in Australia, under the splenor of the Milky Way. The iconic telescope has detected during the last decade a total of 10 mysterious cosmic radio flashes, known as ‘fast radio bursts’. A new study now suggests that these astrophysical sources exhibit a surprising and […]
