There are three major seasons in the life of a bear: the active season, beginning in May; a period of intense eating, in late September, and hibernation, from January into spring.Physiologically, the hibernation period is the strangest, and the most compelling, to researchers. When a bear hibernates,
SpaceX recently launched 60 Starlink satellites as part of its plan to blanket Earth in high-speed internet. But scientists foresee some problems.
A puppy with a tail on his face gained viral fame this week."I would die for Narwhal," a number of Twitter commenters pledged.The rescue mutt was named for a marine mammal with a single tusk that sticks out of its face. But instead of a tusk, Narwhal the puppy has a miniature tail flopping
NASA discovered that a class of microbes can turn CO2 into protein the same way plants do. The resulting powder could replace soy or pea protein.
There are fastballs, and then there are cosmic fastballs. Now it seems that the strongest arm in our galaxy might belong to a supermassive black hole that lives smack in the middle of the Milky Way.Astronomers recently discovered a star whizzing out of the center of our galaxy at the seriously blinding
In the fall of 2015, a rash of posters appeared around Copenhagen. One, in pink letters laid over an image of chicken eggs, asked, "Have you counted your eggs today?" A second -- a blue-tinted close-up of human sperm -- inquired, "Do they swim too slow?"The posters, part of a campaign
Sometimes the Leonids treat skywatchers to meteor storms, with thousands of shooting stars each hour. They glow green as their metals ignite.
Boeing is in line to get paid substantially more per seat than SpaceX for astronaut trips to the International Space Station, in part because it negotiated an increase in what was meant to be a fixed-cost contract, NASA's Office of the Inspector General says in a watchdog report. The 53-page report
KENT, Wash. — The City of Kent's newest lunar rover wouldn't stand up to the radiation-blasted conditions on the surface of the moon, but it's designed to endure a testing ground that's nearly as harsh: a park playground. A kid-friendly reproduction of the moon buggies that transported
A new report reveals that 50% or more of insects have disappeared since 1970 due to habitat loss and pesticide use.
Recreational marijuana is legal in 11 states, and some Democratic presidential candidates have said the drug should become legal nationwide.
SpaceX went the distance today with a static-fire test of its Crew Dragon space taxi's launch escape system — the same type of test that ended in a costly explosion when it was conducted in April. A photo released after the firing shows the Crew Dragon's SuperDraco thrusters blazing away on the
Japan's Hayabusa 2 spacecraft and its science team bid a bittersweet farewell to the asteroid Ryugu, 180 million miles from Earth, and began the months-long return trip to Earth with a precious set of samples. "This is an emotional moment!" the team tweeted on Tuesday. “It's sad to
The snowman-shaped object that NASA's New Horizons probe flew past nearly a year ago on the solar system's icy fringe now has a Native American name: Arrokoth, a word that means "sky" in the Powhatan/Algonquian language. Arrokoth replaces earlier labels for the Kuiper Belt object, including
A new study reveals that extremely damaging hurricanes are becoming more frequent relative to moderate storms, likely due to climate change.
The Mercury transit won't appear in space again until 2032. But if you want to watch the event, don't look at the sun without protection.
Investigators said vitamin E acetate, an ingredient found in canola, soy, and corn oil, appears to be playing a pivotal role in the spate of vaping-related lung illnesses during a call with reporters on Friday.
The Milky Way is on track to collide with the Andromeda galaxy in about 4 billion years. NASA images reveal what the night sky might look like.
For want of a pin, the use of a spaceship's parachute was lost. That may be a simplistic way to explain why one of the three parachutes on Boeing's CST-100 Starliner space taxi failed to open. It does, however, serve as a cautionary tale about the one obvious glitch in Monday's pad abort
Extreme weather events like hurricanes, droughts, and wildfires are linked to climate change. Such phenomena can be seen from space.
For the first time in more than 40 years, NASA has opened up a pristine sample of moon dirt and rocks that was collected during the Apollo missions. Scientists hope that a close analysis of the material from a 2-foot-long, nearly 2-inch-wide core sample will help astronauts get ready for a new series
The Paul G. Allen Frontiers Group, a division of Seattle's Allen Institute, is making a total of $7.5 million in awards to its latest class of five biomedical researchers. The themes for this year's Allen Distinguished Investigators focus on stem cell therapies and single-cell interactions in
Seattle-based Spaceflight says it's handling the pre-launch logistics for a Japanese satellite that's designed to spray artificial shooting stars into the sky. Tokyo-based ALE's spacecraft is just one of seven satellites due to be sent into orbit from New Zealand as early as Nov. 25, aboard
Boeing says it has submitted its proposal for a lunar lander capable of putting astronauts on the moon by as early as 2024, joining a competition that includes Amazon CEO Jeff Bezos' Blue Origin space venture and most likely SpaceX as well. Today marked the deadline for submissions. NASA says it&
