2016年3月31日 · Peering deep into the dusty heart of our Milky Way galaxy using infrared vision, NASA’s Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Except for a few blue foreground stars, the stars are part of the Milky Way’s nuclear star cluster, the most massive and densest star cluster in our galaxy.

2025年1月17日 · Shapley's goal was to measure the size of the Milky Way — and hence the universe as he saw it — by creating the first official cosmic distance ladder.

4 天之前 · LEDA 1313424, aptly nicknamed the Bullseye, is two and a half times the size of our Milky Way and has nine rings — six more than any other known galaxy. High-resolution imagery from NASA’s Hubble Space Telescope confirmed eight rings, and data from the W. M. Keck Observatory in Hawaii confirmed a ninth.

5 天之前 · A century ago, the Milky Way seemed like everything. Hubble’s work widened our view, influenced Einstein’s thinking on relativity, and fueled modern cosmology. Scientists still rely on Cepheid variables to check cosmic distances. They use advanced telescopes to sharpen these measurements, hoping to resolve the Hubble tension about the ...

2013年11月14日 · NASA’s Hubble Space Telescope has revealed the first visual evidence of how our home galaxy, the Milky Way, assembled itself into the majestic pinwheel of stars we see today.

2018年1月11日 · This Hubble Space Telescope image of a sparkling jewel box full of stars captures the heart of our Milky Way galaxy. Aging red giant stars coexist with their more plentiful younger cousins, the smaller, white, Sun-like stars, in this crowded region of our galaxy’s ancient central hub, or bulge.

5 天之前 · LEDA 1313424, aptly nicknamed the Bullseye, is two and a half times the size of our Milky Way and has nine rings — six more than any other known galaxy. (Image credit: NASA, ESA, Imad Pasha ...

2024年11月15日 · “The Milky Way is pushing back so forcefully that the ram pressure has stripped off most of the original mass of the LMC’s halo. There’s only a little bit left, and it’s this small, compact leftover that we’re seeing now.” ... The team used Hubble’s unique ultraviolet vision to study the halo through the light of 28 distant ...

2 天之前 · Scientists using the Hubble Space Telescope have spotted a record-smashing galaxy wrapped in 9 rings of stars — along with the dwarf galaxy that violently plunged through its center.

2024年11月14日 · In an epic story of survival witnessed by the Hubble Space Telescope, one of our nearest galactic neighbors has crashed through the Milky Way galaxy's gaseous halo and lived to tell the tale. But in the process, this dwarf galaxy, called the Large Magellanic Cloud (LMC), has been stripped of most of its own surrounding halo of gas.
