Groundbreaking images of the Sun give a first-ever detailed view of the interior structure of umbrae — the dark patches in the center of sunspots — revealing dynamic magnetic fields responsible for the plumes of plasma that emerge as bright dots interrupting their darkness.

The sun’s surface is blisteringly hot at 10,340 degrees Fahrenheit — but its atmosphere is another 300 times hotter. This has led to an enduring mystery for those who study the sun: What heats the atmosphere to such extreme temperatures? Normally when you move away from a hot source the environment gets cooler, but some mechanism is clearly at work in the solar atmosphere, the corona, to bring the temperatures up so high.

The acidification of the oceans due to climate change has already been known for its unfortunate impact on marine life. However, the ocean may be vulnerable to another risk that can also affect our rapidly changing climate: sea-floor volcanoes, which have …

via RT.com /April 24, 2015 / A 40-year-old Japanese man has taken responsibility for launching a drone with radioactive material that landed on the roof of the office of Prime Minister Shinzo Abe. He said he took the course of action to protest the government’s nuclear policy The man turned himself in at a police station in Fukui Prefecture – nicknamed Japan’s ‘nuclear corridor’ because it contains 14 reactors lined … Continue reading →

via reuters.com / April 22, 2015 / A drone marked with a radioactive sign was found on the roof of Japanese Prime Minister Shinzo Abe’s office on Wednesday and media said it tested positive for a “minuscule” amount of radiation. The radiation was so low it was not harmful to humans, media quoted police as saying. Public broadcaster NHK said the bomb squad was called in to take away the … Continue reading →

via RT.com / April 21, 2015 / All the eight water transfer pumps (pictured) at the Fukushima 1 nuclear power station have been shut down due to a power outage, leading to a leak of radioactive water into the Pacific Ocean, the plant’s operator said. Tokyo Electric Power Co. (TEPCO) reported a power outage on Tuesday, according to Kyodo news agency. It follows the line of the toxic leaks that … Continue reading →

via Gizmodo.com / April 22, 2015 / The dangerous and unenviable task of cleaning up the Fukushima reactor has hit its latest snag: Two snake-like reconnaissance bots had to be abandoned inside the reactor—after one got stuck and another’s camera was damaged by radiation. The Fukushima cleanup relies almost entirely on robots because radiation levels inside the reactor are still too dangerous for humans. TEPCO, the company managing the efforts, … Continue reading →

Saturn’s moon Titan is the only moon in the solar system that has an atmosphere as thick as Earth’s, consisting of more than 98 percent nitrogen, roughly 1.4 percent of methane, and smaller amounts of other gases. NASA’s Cassini satellite has been circling Saturn since 2004, witnessing more than one-third of its 29-year orbit around the Sun, allowing it to observe the changing of the seasons. However, a new study finds that the seasons are not the only thing changing Titan’s atmosphere: its chemical makeup fluctuates according to the Sun’s 11-year cycle of magnetic activity.
