Is There Gravity in Space?

A quick YouTube search reveals a plethora of floating astronaut videos. They can spin in the air, juggle bubbles of water, and their hair looks ridiculous. It certainly appears that there’s no gravity in space—but appearances are deceiving. Astronauts in orbit are more accurately in free fall. They’re constantly falling towards Earth—which means Earth is […]

Fossil Eggshells Suggest All Dinosaurs May Have Been Warm-Blooded

Were all dinosaurs warm-blooded? Were any of them warm-blooded? The question of endothermy has long been, ahem, a hot topic in paleontology. No doubt a new study, using a recently developed method, will fire up the debate. Unlike cold-blooded ectotherms, endotherms have the ability to regulate their body temperature internally. They generate, conserve and shed […]

Betelgeuse is Dimming and Changing Shape, New Image of Its Surface Reveals

Betelgeuse, a red supergiant located roughly 700 light-years away in the constellation Orion, has been dimming over the last few months. But now, astronomers have found it’s also changing shape. In a new image captured with the European Southern Observatory’s Very Large Telescope (VLT), astronomers captured how much the star has dimmed compared with a […]

What Will a Betelgeuse Supernova Look Like From Earth?

If you stargaze on a clear winter night, it’s hard to miss the constellation Orion the Hunter, with his shield in one arm and the other arm stretched high to the heavens. A bright red dot called Betelgeuse marks Orion’s shoulder, and this star’s strange dimming has captivated skygazers for thousands of years. Aboriginal Australians […]

How Do Stars Produce and Release Energy?

You don’t have to be a scientist to know that stars shine. It’s what they’re known for. But how and why they shine was unknown for thousands of years, and only became clear in the 20th century, as humans puzzled out the power of nuclear fusion. To understand how stars shine, it’s important to know […]

NASA’s Next Potential Discovery Missions are Very Volcanic

Every few years, we get big news from NASA about the potential next wave of solar system exploration. This year, the four finalists for the Discovery Missions were announced and if they all had something in common, it is the volcanoes! Potential missions to Venus, Io and Triton were approved to go forward and two […]

The Heat Goes On: Last Month Was The Warmest January On Record

Last month was the warmest January in 141 years of climate records. That’s according to the latest analysis from scientists at NOAA’s National Centers for Environmental Information.  As the angry, oblong red splotch in the graphic above shows, the abnormal warmth was particularly concentrated in Russia and parts of Scandinavia. Eastern Canada also was particularly […]

Venomous Snot Helps These Jellyfish Sting Without Their Tentacles

If you study toxic jellyfish for a living, you know how to take safety precautions. You dive into the ocean covered in protective gear and know to avoid the venom-laced tentacles. But there was one painful jellyfish encounter that always caught marine biologist Cheryl Ames by surprise. The Tohoku University-based researcher found that if she […]

A Different Kind of Climate Refugee

As deserts expand, sea levels rise and other climate impacts make some regions uninhabitable, tens of millions of people will be displaced from their homes. They won’t be alone. Thanks to human-caused climate change, countless plants and animals will also need to move in order to survive. But as disruptive as climate migration will be […]
