James Webb Space Telescope - NASA Science
2021年12月25日 · In 2003, Hubble provided evidence of a massive planet around a very old star, almost as old as the universe. Such stars possess only small amounts of heavier elements that are the building blocks of planets. This implied that some planet formation happened when our universe was very young, and those planets had time to form and grow big inside their primordial disks, even bigger than Jupiter.

NASA’s Hubble, Webb Probe "Snowstorm" of Debris Around Vega. In 2005, NASA’s Spitzer mapped a ring of dust around Vega, one of the brightest stars in the northern sky.
NASA DAVINCI Mission’s Many ‘Firsts’ to Unlock Venus’ Hidden …
2024年12月16日 · Venus’ super thick atmosphere will slow the probe’s descent, but a parachute will also be released to slow it down further. Most Earth-friendly parachute fabrics, like nylon, would dissolve in Venus’ sulfuric acid clouds, so DAVINCI will have to use a different type of material than previous Venus missions did: one that’s …
Hubble Spies a Cosmic Eye - NASA Science
6 天之前 · This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 2566, which sits 76 million light-years away in the constellation Puppis. A prominent bar of stars stretches across the center of this galaxy, and spiral arms emerge from each end of the bar. Because NGC 2566 appears tilted from our perspective, its disk takes on an almond shape, giving the galaxy the appearance of a ...

For decades, NASA’s planetary science program has advanced scientific understanding of our solar system in extraordinary ways, pushing the limits of spacecraft and robotic engineering design and operation.
Hubble Space Telescope - NASA Science
1990年4月24日 · How did a telescope become a household name and change how we look at the cosmos forever? With over 1.5 million observations and 20,000+ papers published on its discoveries, Hubble is the most productive science mission in the history of NASA.
NASA’s Hubble Celebrates Decade of Tracking Outer Planets
2024年12月9日 · Encountering Neptune in 1989, NASA’s Voyager mission completed humankind’s first close-up exploration of the four giant outer planets of our solar system. Collectively, since their launch in 1977, the twin Voyager 1 and Voyager 2 spacecraft discovered that Jupiter, Saturn, Uranus, and Neptune were far more complex than scientists had imagined. There was a lot […]
NASA's Webb, Hubble Telescopes Affirm Universe's ... - Science@NASA
2024年3月11日 · When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the "Hubble Tension," is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe’s evolution.
Science Overview - NASA Science
The James Webb Space Telescope is a giant leap forward in our quest to understand the Universe and our origins. Webb is examining every phase of cosmic history: from the first luminous glows after the Big Bang to the formation of galaxies, stars, and planets to the evolution of our own solar system.
