By Will Dunham WASHINGTON (Reuters) – Observations by the James Webb Space Telescope are giving scientists a fuller understanding about the composition and evolution of Pluto’s moon Charon, the largest moon orbiting any of our solar system’s dwarf planets. Webb for the first time detected carbon dioxide and hydrogen peroxide – both frozen as solids – on the surface of Charon, a spherical body about 750 miles (1,200 km) in diameter, researchers said on Tuesday.

by Issam Ahmed and Lucie Aubourg Agence France Presse The first stunning images from the James Webb Space Telescope were revealed this week, but its journey of cosmic discovery has only just begun. Here is a look at two early projects that will take advantage of the orbiting observatory’s powerful instruments. – The first stars and galaxies – One of the great promises of the telescope is its ability to study the earliest phase […]
“The dawn of a new era in astronomy has begun as the world gets its first look at the full capabilities of NASA’s James Webb Space Telescope, a partnership with ESA (European Space Agency) and CSA (Canadian Space Agency),” NASA announced on July 12 as the telescope’s first full-color images and spectroscopic data were released. This was during a televised broadcast at 10:30 a.m. EDT (14:30 UTC) on Tuesday, July 12, 2022, from NASA’s Goddard […]
Star light, star bright, the James Webb Space Telescope has seen its first star (though it wasn’t quite tonight) — and even taken a selfie, NASA announced Friday. The steps are part of the months-long process of aligning the observatory’s enormous golden mirror that astronomers hope will begin unraveling the mysteries of the early Universe by this summer. The first picture sent back of the cosmos is far from stunning: 18 blurry white dots on […]
by Issam AHMED WASHINGTON, United States (AFP) — The James Webb Space Telescope has arrived at its cosmic parking spot a million miles away, bringing it a step closer to its mission to unravel the mysteries of the Universe, NASA said Monday. At around 2:00 pm Eastern Time (1900 GMT), the observatory fired its thrusters for five minutes to reach the so-called second Lagrange point, or L2, where it will have access to nearly half […]
https://youtu.be/BgxmhTHnvbQ by Lucie AUBOURG The most powerful space telescope ever built completed a tricky two-week-long deployment phase Saturday, unfolding its final golden mirror panel, as it readies to study every phase of cosmic history. Engineering teams in the James Webb Space Telescope’s control room cheered as confirmation came back that its final wing was deployed and latched into place. “I’m emotional about it — what an amazing milestone,” Thomas Zurbuchen, a senior NASA engineer, said […]
by Issam AHMED WASHINGTON, United States (AFP) — The James Webb Space Telescope fully deployed its tennis-court sized sunshield Tuesday, a critical milestone for the success of its mission to study every phase of cosmic history, NASA said. “All five layers of the sunshield are fully tensioned,” said an announcer at the observatory’s control center in Baltimore, where team members cheered, a live feed showed. The 70-foot (21 meter) long, kite-shaped apparatus acts like a […]
by Pierre CELERIER The world’s most powerful space telescope on Saturday blasted off into orbit, headed to an outpost 1.5 million kilometres (930,000 miles) from Earth, after several delays caused by technical hitches. The James Webb Space Telescope, some three decades and billions of dollars in the making, left Earth enclosed in its Ariane 5 rocket from Kourou Space Centre in French Guiana. “What an amazing day. It’s truly Christmas,” said Thomas Zurbuchen, head of […]
by Ludovic EHRET PINGTANG, China (AFP) — Nestled among the mountains in southwest China, the world’s largest radio telescope signals Beijing’s ambitions as a global centre for scientific research. The Five-hundred-metre Aperture Spherical Telescope (FAST) — the only significant instrument of its kind after the collapse of another telescope in Puerto Rico this month — is about to open its doors for foreign astronomers to use, hoping to attract the world’s top scientific talent. The […]
by Marlowe Hood and Laurence Coustal PARIS, France (AFP) — Astronomers on Wednesday unveiled the first photo of a black hole, one of the star-devouring monsters scattered throughout the Universe and obscured by impenetrable shields of gravity. The image of a dark core encircled by a flame-orange halo of white-hot plasma looks like any number of artists’ renderings over the last 30 years. But this time, it’s the real deal. “The history of science will […]
by Kerry SHERIDAN Agence France Presse TAMPA, United States (AFP) — The US space agency’s Kepler space telescope has run out of fuel and is being retired after nine and a half years, having helped discover more than 2,600 planets, some of which may hold life, officials said Tuesday. The unmanned space telescope, which launched in 2009, revealed that billions of hidden planets are in space and revolutionized humanity’s understanding of the universe, experts said. […]
WASHINGTON, United States (AFP) — The Hubble space telescope, which has been in orbit since 1990, has temporarily suspended operations because of a gyroscope failure, the US space agency said Monday. The National Aeronautics and Space Administration (NASA) said Hubble went into “safe mode” on Friday. “Hubble entered safe mode after one of the three gyroscopes actively being used to point and steady the telescope failed,” NASA said in a statement. “Safe mode puts the […]
