We already knew that the solar wind, a flood of energetic particles constantly flowing away from the sun, speeds up as it leaves the sun’s outermost layer. New measurements from the probe showed that the wind is even faster than expected, and strange features spotted in the sun’s magnetic field might help explain why.

You probably do not need much reminding about America’s opioid crisis; the numbers are huge. CDC figures state that there are 100 million adults in the United States (US) affected by chronic pain, and over $600 billion a year are spent on health care costs related to pain and lost productivity. There were over 49,000 deaths associated with opioids in 2017—19,000 of which came from prescribed opioids.
A catastrophic asteroid impact big enough to wipe out humanity is only a matter of time, according to one top scientist. Humanity has next-to no defense against such an impact, Professor Alan Fitzsimmons said, which threatens to end life on Earth. Speaking to the BBC, the astrophysicist warned that the planet is at risk of a deadly disaster if protective measures aren't put in place.
Since the moon is Earth's closest celestial neighbor, we've been able to learn more about it than any other in the solar system. There are surprising details about the moon, such as how in 1958, the US proposed exploding a nuclear bomb on its surface, for clout. Here are 10 scientific and historical facts about the moon that might surprise you.
Every December 8 for years, Julia Robinson blew out the candles on her birthday cake and made the same wish: that someday she would know the answer to Hilbert’s 10th problem. Though she worked on the problem, she did not care about crossing the finish line herself. “I felt that I couldn’t bear to die without knowing the answer,” she told her sister.
Doctors have placed humans in suspended animation for the first time, as part of a trial in the US that aims to make it possible to fix traumatic injuries that would otherwise cause death. Samuel Tisherman, at the University of Maryland School of Medicine, told New Scientist that his team of medics had placed at least one patient in suspended animation, calling it “a little surreal” when they first did it.
Astrophysicist Dr. Natasha Hurley-Walker, from the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR), created the images using the Pawsey Supercomputing Centre in Perth. "This new view captures low-frequency radio emission from our galaxy, looking both in fine detail and at larger structures," she said. "Our images are looking directly at the middle of the Milky Way, towards a region astronomers call the galactic center."
What makes this moon so alluring is the possibility that it may possess all of the ingredients necessary for life. Scientists have evidence that one of these ingredients, liquid water, is present under the icy surface and may sometimes erupt into space in huge geysers. But no one has been able to confirm the presence of water in these plumes by directly measuring the water molecule itself. Now, an international research team led out of NASA's Goddard Space Flight Center in Greenbelt, Maryland, has detected the water vapor for the first time above Europa's surface.
Two longtime spaceflight experts told a group of congressional representatives that NASA needed stronger leadership to meet its ambitious 2024 lunar-landing goal, much less to put humans on Mars. That testimony came during a meeting of the House Committee on Science, Space and Technology's space and aeronautics subcommittee held on Wednesday (Nov. 13).
Put a big red circle on your calendar for Thursday night (Nov. 21), for skywatchers will be out in force, anxiously waiting for and hoping to get a view of a meteor shower that almost nobody has heard of. But the Alpha Monocerotids are this autumn's skywatching wild card.
