Why does SpaceX keep trying to land rockets on floating barges?The latest SpaceX attempt to land a Falcon 9 rocket on a drone barge resulted in an explosion. The company continues to use drone barges, despite having demonstrated a successful ground-based landing, mainly because of physics.
Astronomers befuddled by mysterious flickering starAfter a star's strange flickering and dimming behavior was recently observed, scientists have been trying to explain it. They are still looking for a feasible explanation.
First LookHow geckos might show there's no such thing as SpidermanScientists studied 225 climbing animal species and found that geckos may be the largest animals capable of scaling vertical, smooth walls.
How erupting underwater volcanoes ended 'Snowball Earth' and gave rise to lifeA new study has found that a period of rapid warming that gave rise to animal life may have been accelerated by deep-sea volcanoes.
Why are these sea turtles flying south for the winter?Warm December weather meant hundreds of sea turtles along the US east coast were caught in cold winter weather. So a network of aquariums, biologists, and volunteers in Boston and in North Carolina have been moving them south.
Temperatures rising: How humanity's heat output affecting our oceansScientists have found that the amount of man-made heat absorbed by the world’s oceans has doubled over the last 18 years, causing water temperatures to rise and more heat to be trapped across Earth's climate.
First LookCosmic quintet: Five bright planets to align in a rare celestial treatIn a rare alignment, all five planets in our solar system that are visible to the naked eye will appear in the sky together later this month.
First LookHow did 'Snowball Earth' end? Scientists blame underwater volcanos.Researchers say explosive underwater volcanos may explain the end of the most severe ice age known on Earth and paved the way for life as we know it.
Your home may host 100 different 'quiet and benign' bugs, scientists sayIn an unprecedented analysis of arthropod biodiversity inside the human home, a group of entomologists found that there are on average about 100 different species of bugs in every house.
First LookThe oceans are heating up more rapidly than we thought. Why that matters.The deep ocean has warmed as much in the past two decades as it did in the previous 100 years, researchers found.
First LookZinnias bloom on space station: What does it take to grow plants in space?Space gardening, says NASA, is critical to future space exploration.
Oceans absorb twice as much heat as in 1997, scientists sayThe world's oceans absorb more than 90 percent of the heat energy from global warming. And the amount of heat absorbed has doubled in under 20 years, according to a new study.
Five faces, one worm: Scientists uncover genetic oddityResearchers have identified several species of nematode that can develop different mouths based on their respective environments – all without changing their genetic code.
First LookSpaceX rocket crashes on landing: What went wrong?The Falcon 9 rocket successfully dropped a satellite into orbit Sunday, but tipped over and exploded into pieces when it tried to land on a floating barge in choppy seas about 200 miles west of San Diego.
- SpaceX sea landing failure. Elon Musk explains
Sunday evening, Elon Musk posted a video of the moment SpaceX's Falcon 9 rocket landed on a floating ocean barge, toppled over and exploded into pieces.
Can cosmic particles in pyramids solve the mystery of how they were built?Researchers will try a technology used to peer inside volcanoes to find hidden chambers in pyramids.
SpaceX rocket launches satellite to orbit, but fails to stick landingSpaceX successfully orbited an ocean-monitoring satellite, but the company's attempts to return a rocket stage for reuse fell just short.
What can we learn from our galaxy's second-biggest black hole?Researchers say their discovery 200 lightyears from the galaxy's largest black hole may help answer the question of how supermassive black holes evolve at the center of most large galaxies.
NASA first: Zinnia flower blooms aboard space stationSuccessfully growing flowers in space brings explorers one step closer to growing fresh produce on long space missions.
SpaceX launch ocean-monitoring satellite, attempt ocean landingThe aerospace company's craft is scheduled to launch Sunday morning to deliver an ocean-monitoring satellite into orbit, before a stage of the rocket returns to Earth to attempt a vertical landing at sea.
