A new study published on April 26, 2018, suggests that TRAPPIST-1e, an exoplanet orbiting the red dwarf star TRAPPIST-1, has a large iron core. This could mean that the planet TRAPPIST-1e may have a protective magnetosphere Notes 1 as we have here on Earth.Continue reading TRAPPIST-1e has an Iron Core
NASA has published a video titled “Earth’s Biosphere: The Green Marble”, showing the monthly averages of land greenness (vegetation) and ocean chlorophyll. You can watch how the primary producers (plants and phytoplankton) transform the Earth’s landmasses and oceans over 12 months.
Using data provided by Lunar Reconnaissance Orbiter spacecraft Notes 1 since 2009, NASA has published an amazing virtual Moon tour in 4K Ultra HD Notes 2. As the visualization moves around the near side, far side Notes 3, north and south poles, interesting features, sites, and information gathered on the lunar terrain get highlighted.
46 years ago today, on April 16, 1972, the huge, 363-feet (110.6 meters) tall Apollo 16 (Spacecraft 113/Lunar Module 11/Saturn V Notes 1 SA-511) space vehicle was launched from Pad A, Launch Complex 39, Kennedy Space Center, Florida, at 12:54 p.m. EST. Crewed by Commander John W. Young, Lunar Module Pilot Charles Duke Notes 2, and Command Module Pilot Ken Mattingly Notes 3, it was the tenth manned mission in the United States Apollo space program, the fifth and penultimate to land on the Moon and the first to land in the lunar highlands.

NASA Astronaut Andrew Jay “Drew” Feustel, who is currently living and working aboard the International Space Station, published a photo on his Twitter account with a replica of the “Moon Landscape” drawing by Holocaust victim Petr Ginz to honor Holocaust Remembrance Day (Yom HaShoah). The replica of the painting was first flown in space by Ilan Ramon (June 20, 1954 – February 1, 2003), the first Israeli astronaut for NASA. Ramon has died in the re-entry accident of STS-107, the fatal mission of the Space Shuttle Columbia. Ilan Ramon’s mother and grandmother were Auschwitz survivors, and his grandfather and other family members perished in Nazi death camps.
Feustel took with him to space a copy of a special drawing entitled “Moon Landscape”, which was created by a Jewish Czech boy named Petr Ginz (1 February 1928 – 28 September 1944) while incarcerated in Terezin, Czechoslovakia, during World War II. The drawing depicts how Earth would look from the surface of the moon. Petr was fascinated by science fiction and inspired by his favorite author, the French novelist, poet, and playwright Jules Verne (8 February 1828 – 24 March 1905), to draw and write stories about a far-off world he would never visit. At the age of 16, Petr lost his life at Auschwitz.Continue reading Astronaut Honors Holocaust Remembrance Day from space with “Moon Landscape” drawing by Holocaust victim Petr Ginz
During the STS-68 mission (September 30-October 11, 1994), the crewmembers of Space Shuttle Endeavour used a 70 mm camera to photograph Klyuchevskaya Sopka (also known as Kliuchevskoi), a stratovolcano, the highest mountain on the Kamchatka Peninsula of Russia and the highest active volcano of Eurasia. The eruption was new when this photo was taken. It was photographed from 115 nautical miles (213 kilometers) above Earth.
The sea ice cover blanketing the Arctic Ocean and nearby seas thickens and expands during the fall and winter each year. It reaches its maximum yearly extent in February or March. This year (2018), on March 17, the Arctic sea ice cover peaked at only 5.59 million square miles (14,478,033.54 km2), the 2nd lowest max on record. It is only about 23,200 square miles (60,000 square kilometers) larger than the record low maximum reached in last year, on March 7, 2017.
This continues a trend of shrinking sea ice, with the four lowest Arctic sea ice maximum extents on record in the last four years. In the video published by the NASA Goddard Channel, Climatologist,
This week, NASA’s Mars Curiosity Rover celebrated its 2,000th Martian day (or Sol) on the Red Planet. The nuclear-powered rover was launched from Cape Canaveral on November 26, 2011, and landed on Aeolis Palus in Gale Crater on Mars on August 6, 2012. A Mars day is slightly longer than a day here on Earth: a sidereal day is 24 hours, 37 minutes, and 22 seconds (on Earth, it is 23 hours, 56 minutes and 4.1 seconds) and a solar day is 24 hours, 39 minutes, and 35 seconds (on Earth, 24 hours).
Will we ever visit other stars? Maybe, in the distant future, if humans won’t become extinct, our grand grand … (insert a hundred or a thousand
