保护地球，探索宇宙，发现文明
A complicated web of dark filaments is seen against a light background. When many filmaments intersect, an orange spot is seen. Please see the explanation for more detailed information.
在浅色的背景下可以看到一个复杂丝缕状黝黑暗物质网。当丝缕状暗物质相交时，可以看到一个橙色的板块。有关更多详细信息，请参阅说明。

2023年5月31日 Simulation: A Disk Galaxy Forms Video Credit: TNG Collaboration, MPCDF, FAS Harvard U.; Music: World’s Sunrise (YouTube: Jimena Contreras) Explanation: How did we get here? We know that we live on a planet orbiting a star orbiting a galaxy, but how did all of this form? Since our universe moves too slowly to watch, faster-moving computer sim...
2022年5月29日 Simulation TNG50: A Galaxy Cluster Forms Video Credit: IllustrisTNG Project; Visualization: Dylan Nelson (Max Planck Institute for Astrophysics) et al. Music: Symphony No. 5 (Ludwig van Beethoven), via YouTube Audio Library Explanation: How do clusters of galaxies form? Since our universe moves too slowly to watch, faster-moving computer simulatio...
2022年3月16日 The Observable Universe Illustration Credit & Licence: Wikipedia, Pablo Carlos Budassi Explanation: How far can you see? Everything you can see, and everything you could possibly see, right now, assuming your eyes could detect all types of radiations around you — is the observable universe. In light, the farthest we can see comes from t...
2021年10月31日 Dark Matter in a Simulated Universe Illustration Credit & Copyright: Tom Abel & Ralf Kaehler (KIPAC, SLAC), AMNH Explanation: Is our universe haunted? It might look that way on this dark matter map. The gravity of unseen dark matter is the leading explanation for why galaxies rotate so fast, why galaxies orbit clusters so fast, why grav...

2020年10月23日 Supernova in NGC 2525 Image Credit: NASA, ESA, A. Riess (STScI/JHU) and the SH0ES team Acknowledgment: M. Zamani (ESA/Hubble) Explanation: Big, beautiful, barred spiral galaxy NGC 2525 lies 70 million light-years from the Milky Way. It shines in Earth’s night sky within the boundaries of the southern constellation Puppis. About 60,000 light...
2020年9月20日 Breaking Distant Light Image Credit: VIMOS, VLT, ESO Explanation: In the distant universe, time appears to run slowly. Since time-dilated light appears shifted toward the red end of the spectrum (redshifted), astronomers are able to use cosmological time-slowing to help measure vast distances in the universe. Featured, the light from distant galax...
