‘Young Earths’ might be easier to find than we thought

June 7th, 2020

A new study suggests that Earth-like planets may be easy to spot in space when they’re very young. Rocky worlds originate as “magma oceans” that put off enough heat to be detectible using infrared technology. Going forward, we may be able to catalog many new worlds that will eventually become Earth-alikes. Astronomers that hunt for …

What are the odds of intelligent life existing outside of Earth?

May 19th, 2020

An astronomer has calculated what he believes are the odds that life exists elsewhere in the universe, and they’re quite favorable. Based on his calculations, David Kipping of Columbia University says the odds of some form of extraterrestrial life are around 9:1 in favor. The odds of intelligent life, while still favorable, are lower at …

Europa’s hidden ocean supported by decades-old data

May 14th, 2020

Jupiter’s moon Europa may have a vast ocean of water beneath its surface, and new data from Galileo supports that theory. Researchers found that a lack of protons over Europa’s north pole could indicate an active water plume. Tidal forces prevent the water from freezing, but whether life exists there remains a mystery.

Hope for life on Mars dealt a huge blow by new study

May 12th, 2020

Scientists built a climate model to simulate puddles of salty water on Mars which could hold life. The data doesn’t favor the existence of life as we know it, and the puddles are believed to only exist during certain times of the year. Visit BGR’s homepage for more stories. Of all the planets in our …

Lava tubes on Mars could act as prebuilt homes for astronauts

May 12th, 2020

Crewed missions to Mars may rely on extinct lava tubes to provide shelter from radiation. Researchers tested how well lava caves on Earth block radiation and suggest that the same structures on Mars would make suitable homes. Visit BGR’s homepage for more stories. Humans are headed to Mars, and we might be going sooner than …

Could Mars missions bring alien viruses back to Earth?

May 11th, 2020

NASA is well aware of the risks of bringing samples back from Mars, and is taking precautions to ensure no microbial life gets loose. Samples from the Red Planet will be treated “as though they are the Ebola virus” while being handled by scientists. Visit BGR’s homepage for more stories. We’re in the middle of …

Scientists discovered an animal that doesn’t need oxygen

May 11th, 2020

Scientists have found a multicellular organism capable of surviving without oxygen. The creature, a tiny parasite that lives inside of salmon, doesn’t have the genes for mitochondria, which power our cells and allow for cellular respiration that uses oxygen. Researchers still aren’t sure how the creatures are surviving, so this won’t be the last you …

Rivers flowed on Mars for at least 100,000 years, researchers say

May 7th, 2020

Mars had vast rivers of flowing water for tens of thousands of years, scientists now say. The discovery is based on images sent back by NASA’s Mars orbiter which revealed sediment deposits and telltale signs of flowing water on the surface of the planet. The rivers date back 3.7 billion years, so it will be …

Life could exist on worlds we find hostile, scientists say

May 5th, 2020

Hydrogen-rich worlds may host life, according to a new research paper that shows microorganisms not accustomed to an atmosphere of hydrogen can survive and reproduce in it. The study proved that E. coli and yeast both continue to live despite the dramatic shift to a 100% hydrogen atmosphere. Going forward, the researchers say we should …
