Amazing Pictures of Venus Passing by the Sun
Source - Space Weather News for Jan. 11, 2014: http://spaceweather.com
VENUS AT INFERIOR CONJUNCTION: Today, Jan. 11th, Venus is at inferior conjunction. That means it is located almost directly between Earth and the sun. Around the world amateur astronomers are taking special precautions to avert eye damage as they photograph Venus passing by the sun in broad daylight.

Sunset Comet
Source - NASA Science News for March 15, 2013
Comet Pan-STARRS has survived its encounter with the sun and is now emerging from twilight in the sunset skies of the northern hemisphere. A NASA spacecraft has beamed back spectacular pictures of a "wild and ragged" tail behind the comet's active nucleus.

Big Picture Science for 01/14/13 - Whither the Weather?
Big Picture Science - Whither the Weather?
ENCORE: We all talk about the weather. And now scientists are doing something about it: providing more accurate warnings before big storms hit. Discover how smart technology – with an eye on the sky – is taking monster weather events by storm.
Plus, why severe weather events caused by a warming planet may trigger social and economic chaos.
Also, meet the storm chaser who runs toward tornadoes as everyone else flees… and why your cell phone goes haywire when the sun kicks up a storm of its own.
Guests:
- Michael Smith – Meteorologist, founder of WeatherData and author of Warnings: The True Story of How Science Tamed the Weather
- George Kourounis – Explorer and storm chaser
- Jeffrey Scargle – Research astrophysicist in the Astrobiology and Space Science Division at NASA Ames Research Center
- Ken Caldeira – Climate scientist at the Carnegie Institution for Science’s Department of Global Ecology
- Christian Parenti – Contributing editor of The Nation, visiting scholar at the City University of New York, and author of Tropic of Chaos: Climate Change and the New Geography of Violence
This podcast first released September 12, 2011

Chinese Space Station Transits the Sun
Source - Space Weather News for May 14, 2012: http://spaceweather.com
SOLAR TRANSIT: A photographer in France has caught China's experimental space station, the Tiangong-1, passing directly in front of the sun. The photo shows the winged spacecraft backlit by hot plasma as it flits across the solar disk in the neighborhood of giant sunspot AR1476. Check it out on today's edition of http://spaceweather.com.
TIANGONG-1 SIGHTINGS: The Tiangong-1 is much smaller than the International Space Station. Nevertheless, it can be seen with the naked eye shining in the night sky as brightly as the stars of the Big Dipper.

Spectacular Sundiving Comet
Source - Space Weather News for Dec. 15, 2011: http://spaceweather.com
SUNDIVING COMET: Comet Lovejoy is plunging toward the sun, and its ~200-meter wide core is vaporizing furiously as it approaches the hot star. So far the comet's brightness seems to be exceeding expectations. Indeed, there is a slim chance that the sundiver will brighten enough to be seen with the naked eye in broad daylight on Dec. 15th. Check http://spaceweather.com for further discussion and the latest movies from the Solar and Heliospheric Observatory.
