哈勃太空望远镜

Happy #FourthOfJuly from Hubble! 🇺🇸 Stars shine red, white, and blue in this new Hubble image of globular cluster ESO 591-12, or Palomar 8. Globular clusters are spherical collections of tens of thousands to millions of stars bound tightly together by gravity. They are typically formed in gas and dust-rich regions of early galaxies. The multicolor appearance of the globular cluster is due to the differing temperatures of the stars. Hotter stars are bluer, giving off shorter wavelengths of light, and red stars are cooler, emitting longer wavelengths. Image description: Bright stars cluster against a black background. The stars are more densely concentrated in the center of the image. The stars appear mostly white, but bright red and blue stars are also visible sprinkled throughout the image.

Video by @michaelgeorge | How many oblivious penguins will step on your camera if you leave it on the ground? The answer is … a lot. South Georgia island has no permanent human residents and is primarily a haven for wildlife. It’s one of the places where you find wonder (and humor) in nature. Just make sure to disinfect your camera before and after your visit.

Over more than a decade, a total of 15 feet washed ashore along the Salish Sea. This type of mystery, it turns out, requires scientific, rather than criminal investigation. The unsettling discoveries in the area around Vancouver Island prompted talk of serial killers, aliens, and psychics. But the truth is even more unexpected. Find out more at the link in bio.

Great white sharks have been known to swim near Maine’s coast, but recent efforts by Nat Geo Explorer and photographer @brianskerry have led to the capture of what he thinks is the first underwater image of one in the area. The photograph shows a nearly 10-foot-long great white, a suspected juvenile, and offers a rare glimpse into the marine life that inhabits the Gulf of Maine, where populations of great whites are increasing. Learn more about the sighting and what it tells us about their changing geographic range at the link in bio. Photograph by @brianskerry

The roadside scenery on the ive field parkway is second to none. It’s hard to drive on the road simply because the environment is so distracting. Every turn if filled with new views the entire way. • • • 𝐏𝐡𝐨𝐭𝐨 𝐛𝐲 ➩ @tylerwayneglass ━━━━━━━━━━━━━━━━━━━━━━━━ #canada #earth #beautifuldestinations #travel #alberta

🇮🇹🛵🍇🌻 Road tripping through Tuscany was such a dream! Every town we visited had so much charm and beauty, with Montepulciano probably being my favorite. We also spent time in the Arezzo countryside (first picture), which was gorgeous! I would 100% go back to Tuscany and explore more. Where should I put on my bucket list? #tuscanyguide #italytravel | where to visit in Tuscany, Tuscany itinerary, Italy travel guide, Italy itinerary, best towns in Tuscany, Tuscany road trip
