A team of four "aquanauts" will answer questions live today (July 23) from an underwater laboratory located off the coast of the Florida Keys, 62 feet (19 meters) below the water's surface. Japanese astronaut Akihiko Hoshide, NASA astronauts Jeanette Epps and Mark Vande Hei, and French astronaut Thomas Pesquet, from the European Space Agency, are part of NASA's nine-day underwater NEEMO 18 mission.
The expedition is designed to study aspects of physical and behavioral health, and will also include several simulated "spacewalks" outside the seafloor habitat, to test procedures and technologies for future space missions. The live event will begin at 8 a.m EDT (1200 GMT), and will last for approximately 45 minutes.
Today (July 10) marks the 158th birthday of Nikola Tesla, the eccentric inventor-engineer whose pioneering work gave rise to modern-day electrical power and mass communication systems. The Tesla Science Center at Wardenclyffe, located on the site of the inventor's last laboratory on the North Shore of Long Island, New York, is throwing Tesla a party today. The birthday bash, which will include flag raisings and a cake, will be webcast live from 10 a.m. to noon EDT. Event organizers say a special announcement will also be made during the ceremony.
The top of Chile's Cerro Armazones mountain will be blasted to smithereens today to make way for the European Southern Observatory's European Extremely Large Telescope (E-ELT). The mountain is located in Chile's Atacama Desert, one of the driest places on Earth, a spot that the ESO says has excellent night-sky-viewing qualities (it's dry, remote and devoid of light pollution).
A dynamite blast is scheduled for this afternoon (June 19), with live coverage beginning at 12:30 p.m. EDT (16:30 UTC). The blast is expected to shave 59 feet (18 meters) from the peak of Cerro Armazones, where construction will begin later this year on the European Extremely Large Telescope.
Many skywatchers in the Northern Hemisphere will be able to witness a special celestial event this week: A full moon is set to rise on Friday the 13th. But for some, the full moon will be visible tonight (June 12) instead. The moon will officially appear full at 12:11 a.m. EDT on June 13th, so people in the Atlantic or Eastern Time zones of the United States and Canada will see a so-called Honey Moon coincide with the famously unlucky Friday the 13th. But, for those who live further west, the moon will turn full late tonight.
Yet regardless of time zones, skywatchers can tune in to see the full moon via a live webcast from the Slooh community telescope. The two-hour online event will begin at 9:30 p.m. EDT (6:30 p.m. PDT), and will be accompanied by commentary from Slooh astronomer Bob Berman and observatory engineer Paul Cox.
Slooh will broadcast views of the moon from the Institute of Astrophysics of the Canary Islands, on the west coast of Africa, and from the Pontificia Universidad Catolica de Chile, near Santiago, Chile.
NASA is hosting a media teleconference today (May 12) at 12:30 p.m. EDT (9:30 a.m. PDT), to discuss new research results on the stability of the West Antarctic Ice Sheet and its potential contribution to future sea level rise.
The briefing participants are:
- Eric Rignot, professor of Earth system science at the University of California, Irvine, and glaciologist at NASA's Jet Propulsion Laboratory in Pasadena, California;
- Sridhar Anandakrishnan, professor of geosciences at Pennsylvania State University, University Park; and,
- Tom Wagner, cryosphere program scientist with the Earth Science Division of NASA's Science Mission Directorate in Washington.
The White House is teaming up with the Weather Channel today (May 8) to host a discussion about the current state of climate science, and to examine the results of a sweeping new report on the regional effects of global warming. The live Google+ Hangout begins at 2 p.m. EDT, and will feature weather experts and White House officials.
Participants in today's discussion will include: Carl Parker, a hurricane specialist at the Weather Channel; Kathy Sullivan, administrator of the National Oceanic and Atmospheric Administration (NOAA); Dan Utech, from the White House Domestic Policy Council; Mike Boots, from the White House Council on Environmental Quality; and Laura Petes, from the White House Office of Science and Technology Policy.
Is there life after death? Tonight (May 7) at 6:45 p.m. EDT, a group of doctors and scientists will offer their take on the mystery of human consciousness, the meaning of near-death experiences and the possibility of life after death. The debate, hosted by the NPR show "Intelligence Squared," will be moderated by ABC News correspondent John Donvan.
The White House is hosting an online event today (May 6) to highlight the findings of a newly released report on the impacts of climate change.
The Third U.S. National Climate Assessment details the regional effects of climate change and examines the potential impacts of global warming on the national economy. The report found that all parts of the country are being affected by human-caused climate change, ranging from more intense heat waves to torrential rainfall to sweeping wildfires.
The event, which begins at 2 p.m. EDT, will feature remarks from senior White House officials, as well as commentary from experts who contributed to the National Climate Assessment. [Read full story of the report's findings]
This month, you can fly along the Gulf of Mexico seafloor and explore a strange ecosystem fueled by chemicals instead of sunlight, all from your computer.
The planned exploration will occur roughly south of the Flower Garden Banks National Marine Sanctuary, offshore of Galveston, Texas.
Live video feeds will broadcast from the shipwrecks on April 15, 16 and 24, according to a statement from NOAA. Researchers will explore a deep-sea canyon on April 22. [Read full story on the Expedition]
Pilots André Borschberg and Bertrand Piccard, the two Swiss adventurers who flew a solar-powered plane, called Solar Impulse, on a record-setting coast-to-coast flight across the United States last summer, will unveil their next-generation solar plane today (April 9), in a ceremony beginning at 9 a.m.. EDT (3 p.m. local time in Switzerland).
Borschberg and Piccard are planning to fly the new solar plane, named Solar Impulse 2, on a first-of-its-kind journey around the world.
The original Solar Impulse plane was the first aircraft capable of flying day and night without using any fuel. The ultra-lightweight plane is powered entirely by solar panels and onboard batteries, which charge during the day to allow the plane to continue flying when the sun goes down. The Solar Impulse initiative is designed to demonstrate the vast potential of clean and sustainable energy solutions. [Read more about Solar Impulse]
The Global Precipitation Measurement (GPM) mission's Core Observatory launched on Feb. 27 at noon EST from the Tanegashima Space Center in Japan.
The joint mission, between NASA and the Japan Aerospace Exploration Agency, "set a new standard for precipitation measurements from space, providing the next-generation observations of rain and snow worldwide every three hours," according to NASA officials. "The GPM mission data will advance our understanding of the water and energy cycles and extend the use of precipitation data to directly benefit society."
Check out the video below for an overview of the GPM mission.
Bill Nye Debates Creationist Ken Ham:
Bill Nye the Science Guy is debating creationist Ken Ham Tuesday night (Feb. 4) and you can watch it live here.
The 7:00 p.m. EST showdown is happening on Ham's home turf, at the Creation Museum which he founded in Petersburg, Ky. Moderated by CNN's Tom Foreman, the debate centers around the question "Is creation a viable model of origins in today's modern scientific era?" and will feature questions from the audience.
Nye is a longtime science communicator and the current CEO of the Planetary Society. His opponent is a "young Earth" creationist who reads everything in the Biblical book of Genesis as literal truth. You can read more about the debate here.
