Explosive star death witnessed by Hubble could help develop an early warning system

Astronomers had an unprecedented front-row seat to the explosive death of a star 60 million light-years away. They witnessed the event thanks to telescopes on the ground and in space, including the Hubble Space Telescope. These observations not only provided groundbreaking insight into what happens before a star dies, but could also help astronomers develop…

NASA’s Lucy mission struggles with solar array issue after launching to space

The first NASA mission that will fly by eight ancient asteroids launched early Saturday morning, but not everything went according to plan once the Lucy spacecraft reached space. After Lucy successfully separated from the rocket, it deployed both solar arrays. However, NASA only received confirmation that one of the solar arrays fully unfurled and latched.…

The world is banking on giant carbon-sucking fans to clean our climate mess. It’s a big risk.

The windswept valleys surrounding the Hengill volcano in southwestern Iceland are dotted with hot springs and steam vents. Hikers from all over the world come here to witness its breath-taking scenery. Even the sheep are photogenic in the soft Nordic light. Right in the middle of all that natural beauty sits a towering metal structure…

A ray gun-like device helps scientists see plants in a different light

Scientists are aiming little ray gun-like devices, called leaf clips, at plants in an attempt to better understand biodiversity as environments respond to the climate crisis. Not unlike the tricorder used to perform environment scans in “Star Trek,” the nifty gadget is a type of spectroradiometer that helps record how plant leaves reflect light differently…

NASA’s Lucy mission is ready to launch and explore never-before-seen asteroids

The first NASA mission to fly by a total of eight ancient asteroids is ready for launch. Weather conditions will be 90% favorable on the morning of October 16, when the Lucy mission is set to leave Cape Canaveral Space Force Station at 5:34 a.m. ET. If it doesn’t launch at that time, the window…

Over a thousand cosmic explosions traced to mysterious repeating fast radio burst

Talk about a cosmic temper tantrum. An outburst of explosions has been traced back to a mysterious repeating fast radio burst in space called FRB 121102. Using China’s Five-hundred-meter Aperture Spherical radio Telescope, or FAST, researchers detected 1,652 bursts over the course of 47 days, between August 29 and October 29, 2019. This is the…

New findings a ‘complete reversal’ in understanding why Earth became hospitable to life and its ‘twin’ didn’t

Venus may be a sweltering wasteland today, but scientists have questioned whether the planet was always so inhospitable. While previous studies suggested Venus might have once been covered in oceans, new research has found the opposite: Venus has likely never been able to support oceans. Researchers also determined that a similar story could have played…

Our underwater future: What sea level rise will look like around the globe

The planet is warming rapidly, resulting in historic drought, deadly floods and unusual melting events in the Arctic. It is also causing steady sea level rise, which scientists say will continue for decades. A new study from Climate Central, a nonprofit research group, shows that roughly 50 major coastal cities will need to implement “unprecedented”…

Scientists looked at more than 100,000 studies and found the world has a giant climate-crisis blind spot

Scientists using artificial intelligence to sift through around 100,000 climate studies were trying to put a number on how many people in the world were already experiencing the impacts of the climate crisis. Instead, they discovered something else: there is a worrying inequality in the world of climate science. Climate change studies are twice as…

England to remove another ‘discriminatory’ barrier to blood donation

England is set to remove an “outdated, unnecessary and actively discriminatory” question from blood donor forms, which campaigners say has predominantly affected Black communities’ ability to give blood. It comes after UK-wide changes in June made it easier for sexually active gay and bisexual men to give blood — overturning a ban that originated during…
