Next-generation space telescopes could be built off-planet

The Hubble Space Telescope was visited by astronauts between 1993 and 2009 during five space-shuttle missions. Here, two space astronauts work on Hubble during the first maintenance mission, fixing the telescope's mirror and installing a new camera. Credit: NASA When it comes to telescopes, size matters. To keep learning about the universe, astronomers are increasingly interested in building larger and …

The future of space astronomy may depend on two large ground telescopes

This article was originally published in the January 21, 2019 issue of the SpaceNews magazine. At the largest conference of astronomers in the United States, the largest astronomy mission under development was virtually a non-appearance. The partial government shutdown, which began on December 22, prevented NASA officials from attending the January 2010 American Astronomical Society (AAS) winter convention in Seattle. …

Holy Cow! Mysterious Blast Studied with NASA Telescopes

A letter and unusual flash spotted in the night sky on June 16, 2018, puzzled astronomers and astrophysicists across the globe. The event – called AT2018cow and nicknamed "the Cow" after the coincidental final letters in its official name – is unlike any celestial outburst ever seen before, prompting multiple theories about its source. Over three days, the Cow produced …

Modular Inflatable Composites for Huge Space Telescopes – NextBigFuture.com

There is a growing need to build telescopes and structures for the observation of exoplanets, main-belt asteroids, and NEOs. Space observation capabilities can be significantly enhanced by large aperture structures. Structures that span several meters could potentially revolutionize observation technologies. These include star apertures for imaging distant objects such as exoplanets and high-resolution, high-aperture telescopes. In addition to size, such …

Small satellites could be a "guiding star" for massive space telescopes

Space Gaze NASA's long-term plans for space telescopes are quite large; in fact, next-generation telescopes will be massive. Apart from our solar system, there are more than 3,900 confirmed planets. To know more about these planets, whether they have oxygen, water or other signs of life, we need larger telescopes with very sensitive instruments and mirrors as large as those …

Researchers Develop CubeSats with Lasers to Provide Uniform Reference Light for Telescopes Scanning for Far Planets – ScienceDaily

Beyond our solar system, there are more than 3,900 confirmed planets. Most of them were discovered due to their "transits" – cases in which a planet crosses its star and blocks its light for a moment. These burglaries in the starlight can tell astronomers about the size and distance of a planet to its star. To learn more about the …

NASA telescopes snatch the Christmas comet, the brightest of 2018

The 46P / Wirtanen comet is 12 million kilometers from Earth. NASA / ESA / D. Bodewits (Auburn University) / J-Y. Li (Planetary Science Institute) If you look up into the sky at this time of year to spot a comet, you may be referring to one of Santa's eight reindeer . However, Christmas 2018 was particularly friendly with folk …

As telescopes, astronomers fear losing their eyes in space;

A – A + By Sarah Kaplan The Washington Post America's Great Observatories – The Hubble, Chandra, Compton and Spitzer space telescopes – have peered into the unknown and made breakthrough discoveries about newborn stars, dark matter and the age of the universe. These telescopes, whose era began in 1990, are aging, if not dead, and there is no budget …

NASA Telescopes may have discovered the first "Exomoon"

The potential Exomoon encircles an exoplanet called Kepler-1625b, which was discovered using NASA's Kepler Space Observatory in a recent study that identified 284 "transiting planets". This is the term for planets that move between the earth and its home star. This causes the light of the star to be darkened from our point of view. This transit method can tell …
