The Vera C. Rubin Observatory has taken another step towards first light, projected for some time in 2022. Its enormous 3200 megapixel camera just took its first picture during lab testing at the SLAC National Accelerator Laboratory. The camera is the largest ever built, and its unprecedented power is the driving force behind the Observatory’s ten year Legacy Survey of Space and Time (LSST).Continue reading “Vera Rubin’s Monster 3200-Megapixel Camera Takes its First Picture (in the Lab)”
Most people with any interest in astronomy know about the Crab Nebula. It’s a supernova remnant in the constellation Taurus, and its image is all over the place. Google “Hubble images” and it’s right there with other crowd favorites, like the Pillars of Creation.
The Crab Nebula is one of the most-studied objects in astronomy. It’s the brightest source of gamma rays in the sky, and that fact is being used to establish the function of a new telescope called the Schwarschild-Couder Telescope.Continue reading “Gamma Rays Detected Coming From the Crab Nebula”
In the mid-2020s, NASA’s next-generation Wide Field Infrared Survey Telescope (WFIRST) will take to space. With unprecedented resolution and advanced instruments, it will build on the foundation established by the venerable Hubble Space Telescope – which celebrated its 30th anniversary this year! In anticipation of all it will accomplish, NASA decided that the WFIRST needs a proper name, one that honors its connection to Hubble.
This week, NASA announced that henceforth, the WFIRST mission will be known as the Nancy Grace Roman Space Telescope (or Roman Space Telescope for short) in honor of Dr. Nancy Grace Roman (who passed away in 2018). In addition to being NASA’s first Chief Astronomer, she was also a tireless educator and advocate for women in STEMs whose work paved the way for space telescopes – leading to her nickname “the mother of Hubble.”Continue reading “WFIRST Will be Named After Nancy Grace Roman, NASA’s First Chief Astronomer”
We’re inching closer and closer to the James Webb Space Telescope’s (JWST) launch date of March 30th, 2021, (or maybe July 2021.) We never thought we’d get this close, with only a year to go before we send this powerful space telescope on its way. Now the telescope has been put in its launch configuration.Continue reading “James Webb is Fully Stowed Into its Launch Configuration”
Japan has suspended its funding contribution to the controversial Thirty Meter Telescope (TMT) in Hawaii. An international consortium is behind the TMT, which was proposed for the summit of Mauna Kea. Mauna Kea is one of the most desirable observing locations on Earth. It’s already host to several observatories, including the Subaru Telescope and the Keck Observatory. The $1.4 billion TMT would be the most powerful telescope there.Continue reading “Japan Suspends its Funding for the 30-Meter Telescope”
Soon, astronomers and astrophysicists will have more observing power than they know what to do with. Not only will the James Webb Space Telescope one day, sometime in the next couple years, we hope, if all goes well, and if the coronavirus doesn’t delay it again, launch and begin operations. But another powerful NASA space telescope called WFIRST has passed an important stage, and is one step closer to reality.Continue reading “WFIRST Passes an Important Milestone, it’s Time to Begin Development and Testing”
The world’s largest and most sensitive radio telescope is officially open for business according to Xinhua, China’s official state-run media. The FAST Radio Telescope saw fist light in 2016 but has been undergoing testing and commissioning since then. FAST stands for Five-hundred meter Aperture Spherical Telescope.Continue reading “China’s 500-Meter FAST Radio Telescope is Now Operational”
Rigorous testing is at the heart of any successful space mission. The James Webb Space Telescope (JWST) will be a million miles away when it deploys its mission-critical sun-shield, and if it doesn’t function as planned, that’s it. Game over.Continue reading “James Webb Tests its Sun-Shield. So Far, So Good.”
After years of construction, China’s new radio telescope is in action. The telescope, called FAST (Five-hundred-meter Aperture Spherical Radio Telescope) has double the collecting power of the Arecibo Observatory in Puerto Rico, which has a 305 meter dish. Until now, Arecibo was the world’s largest radio dish of its type.Continue reading “China’s FAST Telescope, the World’s Largest Single Radio Dish Telescope, is Now Fully Operational”
The U.S. House of Representatives have passed a bill to change the name of the Large Synoptic Survey Telescope (LSST.) Instead of that explanatory yet cumbersome name, it will be named after American astronomer Vera Rubin. Rubin is well-known for her pioneering work in discovering dark matter.Continue reading “Great News! The Large Synoptic Survey Telescope Might be Named for Vera Rubin”
