Astronomy: Hubble Space Telescope At 32 Years

The Hubble Space Telescope celebrated its 32nd year in orbit by premiering a stunning new Hubble image of a collection of five galaxies, known as Hickson Compact Group 40. Even after all these years, Hubble continues to uncover the mysteries of the universe. These are a few science achievements from Hubble’s latest year in orbit.

Science: Gravitational Wave Detectors & Special Oil Spill Cleanup Sponges

Science Staff Writer Adrian Cho joins host Sarah Crespi to talk about plans for the next generation of gravitational wave detectors—including one with 40-kilometer arms. 

 The proposed detectors will be up to 10 times more sensitive than current models and could capture all black hole mergers in the observable universe.

Sarah also talks with Pavani Cherukupally, a researcher at Imperial College London and the University of Toronto, about her Science Advances paper on cleaning up oil spills with special cold-adapted sponges that work well when crude oil gets clumpy.

New Astronomy Books: “Expanding Universe – The Hubble Space Telescope”

With investigations into everything from black holes to exoplanets, the Hubble Telescope has changed not only the face of astronomy but also our very sense of being in the universe. On the 30th anniversary of its launch into low-earth orbit, this updated edition of Expanding Universe presents 30 brand new images, unveiling more hidden gems from the Hubble’s archives.

Expanding Universe - The Hubble Space Telescope - Taschen June 2020

Ultra-high resolution and taken with almost no background light, these pictures have answered some of the most compelling questions of time and space while also revealing new mysteries, like the strange “dark energy” that sees the universe expanding at an ever-accelerating rate.

The collection is accompanied by an essay from photography critic Owen Edwards and an interview with Zoltan Levay, who explains how the pictures are composed. Veteran Hubble astronauts Charles F. Bolden, Jr. and John Mace Grunsfeld also offer their insights on Hubble’s legacy and future space exploration.

The contributors

Charles F. Bolden, Jr., Major General, USMC (Ret.), is a former Administrator of NASA, where he oversaw the completion of the International Space Station. He spent 14 years as a member of NASA’s Astronaut Corps, and commanded and piloted the Space Shuttle Discovery on STS-31, which launched the Hubble Space Telescope into orbit.

Owen Edwards has written about photography for more than 30 years for numerous publications including American PhotographerNew York Times Magazine, and Smithsonian.

John Mace Grunsfeld, PhD, is an astrophysicist and a NASA astronaut. He has flown five times on the Space Shuttle, including three Hubble servicing missions. He has served as the Associate Administrator for the Science Mission Directorate, the NASA Chief Scientist, and as the Deputy Director of the Space Telescope Science Institute.

Zoltan Levay is a retired principle science visuals developer at the Space Telescope Science Institute, where he worked with astronomers and communicators worldwide to publicize science results from NASA’s Hubble Space Telescope.

Top Timelapse Videos: “Observatories – ESO” In Chile By Martin Heck

Filmed, Edited and Directed by: Martin Heck

Music: “Chasing Time” by David A. Molina

Observatories European Southern Observatory ESO in Chile timelapse video by Martin Heck 2019

Part two of a series of journeys to the big astronomical observatories of this planet. In this video: The Paranal Observatory and the Atacama Large Millimeter Array – ALMA. With some of the biggest ground-based telescopes on earth, the observatories of the European Southern Observatory in Chile are at the bleeding edge of astronomical research. These incredibly complex machines, operating synchronized and precisely in the very remote and hostile environments of the Atacama Desert and Andes, enable deep views into the universe.

All the sequences were shot in only 4 nights in total, but on two trips in 2017 and 2019.
