Scientists analyse images over seven decades.
German and Russian scientists say they have documented the life cycle of a volcano for the first time, revealing that it has a kind of “memory”.
The volcano in question is Bezymianny, an active stratovolcano on the Kamchatka peninsula in eastern Russia which suffered a collapse in its eastern sector back in 1956.
Historically, human space exploration was initiated by the Soviet Union with the Sputnik launch into the Earth orbit in 1957. Humankind’s space endeavors grew with more determination after the first animal’s launch, a dog called “Laika”. Marked by the Soviet Union’s Yuri Gagarin trip in the Vostok 1 in 1961 and his compatriot Valentina Tereshkiva’s three-day space orbiting mission in the Vostok 6 in 1963, humankind succeeded to make the giant leap beyond Earth’s boundaries.
Nonetheless, the Yuri Gagarin’s spacewalk and Neil Armstrong’s first steps on the Moon remain the spark to ignite ambitious human prospects on space travel, which unleashed unlimited possibilities on the humankind’s expansion into outer space. The achieved milestones in space endeavors created a shift from a mere inspirational driver and curiosity feeder on existential questions [3] to a space race which grew from a bipolar race between the United States and the former Soviet Union to a different space race in which new actors, particularly private actors, have become essential players [4].
The most prominent ongoing transformation of the global space sector is the race to commercialize space driven by private enterprises and induced by governmental agencies who rewarded these enterprises billions of dollars in governmental space contracts. The evolution of space commercialization could be illustrated through the U.S. space economic emergence from the National Aeronautics and Space administration’s (NASA) monopoly to a more liberalized space sector. Such an emergence came as a consequence of NASA’s struggle to improve its military-based technologies to achieve cost-effective and safe space access [5] in addition to budget reductions and various costly accidents, which led NASA to outsource its spaceship manufacturing.

Just how many planets are visible without a telescope? Not including our own planet, most people will answer “five” (Mercury, Venus, Mars, Jupiter and Saturn).
Those are the five brightest planets, but in reality, there is a sixth planet that can be glimpsed without the aid of either a telescope or binoculars.
NASA has announced it is looking for private companies to go to the moon and collect dust and rocks from the surface and bring them back to Earth.
The American space agency would then buy the moon samples in amounts between 50 to 500 grams for between $15,000 to $25,000.
The NASA administrator, Jim Bridenstine, announced on Thursday that the moon material collection would become part of a technology development program that would help astronauts “live off the land” for crewed missions in the future to the moon or elsewhere.
Canada reported no new deaths from COVID-19 on Friday for the first time in six months. The last time the country reported no new deaths from the virus on March 15, at the start of lockdowns in North America due to the pandemic, Reuters reports.
As of Friday evening, over 6 million people had been tested for COVID-19 in Canada, 2.1% of which came back positive. Some 702 new cases were reported on Friday, but no new deaths, the Public Health Agency of Canada reported.
An early analysis of the data, which did not include patients enrolled later in the trial, found that median time to recovery was 11 days for patients on remdesivir and 15 days for patients on placebo. It also suggested a lower death rate, 8 percent on remdesivir compared to 11.6 percent on placebo, but that difference was just short of statistical significance.
UCSF and Zuckerberg San Francisco General Hospital together enrolled about 30 patients in the NIH trial. Because the trial was double-blinded, neither the doctors nor the patients knew which patients received remdesivir or placebo. With survival rates in San Francisco relatively high compared to harder hit cities, it was hard to attribute any specific improvement to the drug, said Chin-Hong and Doernberg, who both cared for patients in the trial.

Elon Musk has shared some details about future testing of Starship, the SpaceX launch vehicle currently being developed by the company at its Boca Chica, Texas facility. Recently, SpaceX has completed short, 150 meter (just under 500 feet) test flights of two earlier Starship prototypes, SN5 and SN6 – and SN8, which is currently set to be done construction “in about a week” according to Musk will have “flaps & nosecone” and ultimately is intended for a much higher altitude test launch.
The prototypes that SpaceX has flown and landed for its so-called ‘short-hop’ tests over the past few weeks have been full-sized, but with a simulated weight installed on the top in place of the actual domed nosecone that will perch atop the final production Starship and protect any cargo on board. SN5 and SN6, which are often compared to grain silos, are also lacking the large control flaps on either side of the nosecone that will help control its flight. SN8 will have both, according to Musk.
Episode 3: Time Machines – Hubble has looked back billions of years in time to see some of the earliest galaxies in their infancy, and it has fundamentally changed what we know about the universe itself. Find out from Nobel Laureate John Mather and Hubble Senior Project Scientist Jennifer Wiseman how Hubble will work with the future James Webb Space Telescope to revolutionize our understanding of the universe even further.
Nvidia is rumored to be in talks to buy Arm for more than $40 billion from SoftBank, according to a report in the Wall Street Journal.
Because much cancer research and clinical trials have been based on white populations, efforts to explore the ways race and ethnicity influence disease are underway.
