“Yet if hope has flown away In a night, or in a day, In a vision, or in none, Is it therefore the less gone? All that we see or seem Is but a dream within a dream.” “A Dream Within A Dream” by Edgar Allan Poe (1809-1849) There is lot fuzz about the discovery [...]

Japan’s MTSAT-2 (also known as Himawari-7) collected these images of today’s annular solar eclipse from geostationary orbit. The satellite (similar to the United State’s GOES satellites), observed the moon’s shadow as it passed over Australia & the Pacific Ocean. The image sequence begins at 21:32 UTC, with an additional image each hour until 02:32 UTC. [...]

The great French biologist Francois Jacob died on April 19th 2013. I started this post and left it lingering in draft. I want to post it now.
Carl Zimmer at The Loom has an essay which outlines one of the key moments of Jacob's career- when he realized how cells turn genes on and off. That formed the basis of understanding gene regulation and laid the foundation of the field of developmental biology. For that work he shared the Nobel Prize in 1965 with Andre Lwoff and Jacques

This is a partial re-post of my latest in the Guardian's Climate Consensus – the 97%. It's intended as a basic primer to reference the next time somebody tells you global warming is nothing to worry about because climate sensitivity is low.
What you need to know about climate sensitivity
It's a critical aspect of the climate system, but the basics are simple

The people at Google Earth have unveiled a new feature of Earth Engine: time-lapse views of anywhere on Earth using satellite imagery back to 1984. My colleagues on Twitter have been exclaiming all morning:
@rschott: "The Evolving Earth: Meanders & Dunes & Shorelines Oh my!"
@kwinkunks: "Witness Alberta's oil sands development in Google's 100% awesome time-lapse Earth Engine"

Lava flow in the western part of Hawai’i that originated from the Hualalai volcano and formed in 1800…1801 is remarkably rich in xenoliths. It is an aa lava. Many nice examples of dunite and peridotite (rocks from the mantle) can be found with a little bit of patience and searching. This is how they [...]The post Xenoliths in Hawaiian lava appeared first on Sandatlas.

Happy Friday! Here’s a view of the folded contact between the (older, lower) New Market Formation, and the (younger, upper) Lincolnshire Formation, as exposed in Staunton, Virginia: The contact has been folded, pretty intensely: The New Market Formation is massive, light-colored, and exhibits fenestral texture here. The Lincolnshire is darker, more thinly-bedded, and is chock full of fossil invertebrates. Explore it for yourself in this M.A.G.I.C. GigaPan: link A closer …

I came across this post recently and it reminded me of one of the "games" that I played as a little kid.I think I was probably 8 or 9 - old enough that I didn't need to be watched constantly, young enough that I wasn't allowed to wander too far afield. I roped my younger neighbor into a long-running study whereby we waved enthusiastically at every single person who drove by and dutifully recorded whether they waved back, did a weird non-wave acknowledgement of our existence, or ignored us. For […]

Soda straws in Oregon Caves National Monument, early in the on-trail tour.

Every summer, thousands of people drive out to Chincoteague in Virginia to see the beautiful beach, wild ponies, and the stunning National Wildlife Refuge. To get there, they drive around the long NASA runway at the Wallops Island Flight facility, and you can’t help noticing the cluster of big satellite dishes. If you’ve been there, you probably have wondered just what all those dishes are for. Meteorologists already know, and you’re about to find …
