2021年1月12日 · In that vast, previously unexplored region, the probes are tasting space outside the protective bubble of particles and magnetic fields created by our Sun. They crossed over in 2012 and 2018, respectively, becoming the first spacecraft to enter this region. Space Oddities. Our universe includes a variety of astonishing and sometimes bizarre ...

2025年1月31日 · Space telescopes like NASA’s Hubble and Webb have zoomed in on many corners of the universe to show us planets, stars, and galaxies in high resolution. But some questions — like how much light do all the galaxies in the universe collectively emit? — can be answered only by looking at the big picture.

2022年7月12日 · The James Webb Space Telescope launched Dec. 25, 2021, on an Ariane 5 rocket from Europe’s Spaceport in French Guiana, South America. After completing a complex deployment sequence in space, Webb underwent months of commissioning where its mirrors were aligned, and its instruments were calibrated to its space environment and prepared for …

2023年7月12日 · Our own Sun experienced a phase like this, long ago, and now we have the technology to see the beginning of another star’s story,” said Klaus Pontoppidan, who served as Webb project scientist at the Space Telescope Science Institute in Baltimore, Maryland, since before the telescope’s launch and through the first year of operations.

2022年10月12日 · A Wolf-Rayet star is an O-type star, born with at least 25 times more mass than our Sun, that is nearing the end of its life, when it will likely collapse and form a black hole. Burning hotter than in its youth, a Wolf-Rayet star generates powerful winds that push huge amounts of gas into space.

2024年10月31日 · Many space telescopes, including NASA’s Hubble and James Webb, can provide high-resolution, in-depth spectroscopy of individual objects or small sections of space. Other space telescopes, like NASA’s retired Wide-field Infrared Survey Explorer (WISE), were designed to take images of the whole sky. SPHEREx combines these abilities to apply ...

2024年2月14日 · In October 2022, the same magnetar – called SGR 1935+2154 – produced another fast radio burst, this one studied in detail by NASA’s NICER (Neutron Star Interior Composition Explorer) on the International Space Station and NuSTAR (Nuclear Spectroscopic Telescope Array) in low Earth orbit. The telescopes observed the magnetar for hours ...

2025年1月27日 · Cesar Marin, SPHEREx integration engineer, Launch Services Program, NASA’s Kennedy Space Center in Florida Questions can be asked on social media during the briefing using #AskNASA. The SPHEREx observatory will survey the entire celestial sky in near-infrared light to help answer cosmic questions involving the birth of the universe, and the ...

2001年11月26日 · Upcoming missions, such as the JPL-managed Space Infrared Telescope Facility, will aid in understanding this and later stages of star formation. Gravity Moves into Action In the next stage of star development, gravity pulls more and more matter from the surrounding nebula, a concentration of gas and dust, into these clumps. Over a period of ...

2017年10月4日 · Called KIC 8462852, also known as Boyajian's Star, or Tabby's Star, the object has experienced unusual dips in brightness -- NASA's Kepler space telescope even observed dimming of up to 20 percent over a matter of days. In addition, the star has had much subtler but longer-term enigmatic dimming trends, with one continuing today.
