Astronomy: James Webb Telescope First Images

The first images from the James Webb Space telescope have been revealed. Incredibly clear images of the Carina Nebula, the Eight-Burst Nebula, a galaxy cluster called Stephan’s Quintet and an exoplanet named WASP-96b make up the first set of science data from JWST.

Astronomy: James Webb Telescope In The Cosmos

Decades of work, $10 billion in spending and nearly 14 billion years of cosmic history have brought us to this moment. The first science from the James Webb Space Telescope, the largest and most powerful observatory ever built. What questions will it answer? What new mysteries will discover? What will this new eye on the cosmos reveal? The telescope’s first science images will be out VERY soon. Here’s a quick look at what you can expect when they drop.

Science: The Search For Alien Life In The Universe

The thought of finding alien life has fascinated people since the time of the ancient Greeks—but developments in astrobiology could be about to turn this possibility into reality. How do you hunt for life beyond Earth—and might this be the decade when we find it?

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.

Space Exploration: Year 2021 NASA Highlights

2021 was the busiest year yet for NASA in low-Earth orbit, we also made progress preparing for a flight test around the Moon, and had a very active year exploring space, studying Earth, testing technologies for next generation aircraft, and much more. Here’s a look back at those and other things we did this year at NASA. Download Link: https://go.nasa.gov/3yM3so2

Views: James Webb Space Telescope Set To Launch – Will Reveal First Galaxies

The James Webb Space Telescope, a collaboration between NASA, the European Space Agency and the Canadian Space Agency, is set to launch later this month. Scientists say its technology makes it 100 times more powerful than the Hubble and could give it the ability to see back to the first galaxies in the universe. Illustration: Adele Morgan/WSJ

Astronomy: Stunning ‘Butterfly Nebula’ From Hubble Space Telescope


This celestial object looks like a delicate butterfly. But it is far from serene. What resemble dainty butterfly wings are actually roiling cauldrons of gas heated to nearly 20 000 degrees Celsius. The gas is tearing across space at more than 950 000 kilometres per hour — fast enough to travel from Earth to the Moon in 24 minutes! A dying star that was once about five times the mass of the Sun is at the centre of this fury. It has ejected its envelope of gases and is now unleashing a stream of ultraviolet radiation that is making the cast-off material glow. This object is an example of a planetary nebula, so-named because many of them have a round appearance resembling that of a planet when viewed through a small telescope. The Wide Field Camera 3 (WFC3), a new camera aboard the NASA/ESA Hubble Space Telescope, snapped this image of the planetary nebula, catalogued as NGC 6302, but more popularly called the Bug Nebula or the Butterfly Nebula.

WFC3 was installed by NASA astronauts in May 2009, during the Servicing Mission to upgrade and repair the 19-year-old Hubble. NGC 6302 lies within our Milky Way galaxy, roughly 3800 light-years away in the constellation of Scorpius. The glowing gas is the star’s outer layers, expelled over about 2200 years. The “butterfly” stretches for more than two light-years, which is about half the distance from the Sun to the nearest star, Proxima Centauri. The central star itself cannot be seen, because it is hidden within a doughnut-shaped ring of dust, which appears as a dark band pinching the nebula in the centre. The thick dust belt constricts the star’s outflow, creating the classic “bipolar” or hourglass shape displayed by some planetary nebulae. The star’s surface temperature is estimated to be over 220 000 degrees Celsius, making it one of the hottest known stars in our galaxy. Spectroscopic observations made with ground-based telescopes show that the gas is roughly 20 000 degrees Celsius, which is unusually hot compared to a t

Technology: NASA Targets Asteroid With Spacecraft

NASA introduced the space agency’s first planetary defense test mission, the Double Asteroid Redirection Test or DART, a spacecraft they plan to launch later this month on a mission to crash into an asteroid.

NASA Space Missions: Ten Mysteries Of Venus (Video)

The surface of Venus is completely inhospitable for life: barren, dry, crushed under an atmosphere about 90 times the pressure of Earth’s and roasted by temperatures two times hotter than an oven. But was it always that way? Could Venus once have been a twin of Earth — a habitable world with liquid water oceans? This is one of the many mysteries associated with our shrouded sister world. 27 years have passed since NASA’s Magellan mission last orbited Venus. That was NASA’s most recent mission to Earth’s sister planet, and while we have gained significant knowledge of Venus since then, there are still numerous mysteries about the planet that remain unsolved. NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission hopes to change that. Video credit: NASA’s Goddard Space Flight Center

Science: Satellite Swarms Block Astronomers Gaze

For millennia, bright lights sprinkled across our celestial sphere have guided great explorers, passed on storied traditions, and lent insight into the nature of our universe. Now, they have competition: thousands of satellites circling the globe in low orbit. Read the story: https://www.science.org/content/artic…
