Some scientists think so – and a new experiment has shown just how tough some bacteria are

Researchers at Vienna University found that a bacteria, Deinococcus radiodurans, survived for a whole year on a platform outside the nternational Space Station.

The researchers analysed how the bacteria survived the environment of outer space, resisting galactic cosmic and solar UV radiation, extreme vacuum, temperature fluctuations, desiccation, freezing, and microgravity.

The idea of alien life spreading like ‘seeds’ through space isn’t new – the theory is known as ‘Panspermia’.

The new research helps to understand just how far such organisms could travel, the researchers say. 

Tetyana Milojevic, a head of Space Biochemistry group at the University of Vienna says, “These investigations help us to understand the mechanisms and processes through which life can exist beyond Earth, expanding our knowledgow to survive and adapt in the hostile environment of outer space. 

“The results suggest that survival of D. radiodurans in LEO for a longer period is possible due to its efficient molecular response system and indicate that even longer, farther journeys are achievable for organisms with such capabilities.”

The researchers write, “These results should be considered in the context of planetary protection concerns and the development of new sterilisation techniques for future space missions.”

Researchers last year tested a new drug-resistant coating on the International Space Station to fend off potential infections.

Reearchers have warned that bacteria on the space station can get tougher, as they adapt to the harsh conditions in space – as they test a new antimicrobial coating to fight them off. 

‘Spaceflight can turn harmless bacteria into potential pathogens,’ said senior study author Prof. Elisabeth Grohmann of Beuth University of Applied Sciences Berlin. 

‘Just as stress hormones leave astronauts vulnerable to infection, the bacteria they carry become hardier, developing thick protective coatings and resistance to antibiotics, and more vigorous, multiplying and metabolising faster.’

Scientists tested a new antimicrobial coating based on silver and ruthenium – which reduced levels of bacteria on contamination-prone surfaces. 

Grohmann said, ‘After 6 months exposure on the ISS, no bacteria were recovered from AGXX-coated surfaces.

Renewed hopes for humanity in space – The Hill Times

Published

The successful launch of NASA’s SpaceX Crew-1 mission to the International Space Station on Nov. 15 is a symbolic milestone that should be celebrated. Onboard the commercial launch vehicle were American and Japanese astronauts, who joined the other Russian and American crew already residing in the International Space Station, itself a remarkable example of the power of cooperation in space among many countries around the world. As the Falcon 9 soared into space, the collaborative, cooperative and commercial nature of space was once again clear for all to see.

Beaver moon eclipsed by Earth's shadow tonight | Georgia Straight Vancouver's News & Entertainment Weekly – Straight.com

Published

 on


November’s full moon will undergo a partial eclipse after midnight Sunday (November 29) when it slides across the outer (penumbral) edge of Earth’s shadow during the early hours of November 30.

This moon—sometimes called the beaver moon because it comes at a time when beavers are stepping up activities to prepare for the cold winter months ahead—will rise in the east and climb the night sky until the start of the eclipse.

Because the full moon will not cross into the darkest part of our planet’s shadow (the umbra), the eclipse—which will affect about 83 percent of the satellite’s surface—will be seen as a darkening of the affected area.

The partial eclipse will start at 1:42 a.m., when the moon should be high overhead and to the southwest. The moon will take more than four hours to traverse the Earth’s penumbra.

When the moon sets, at 6:56 a.m. Vancouver time, it should be coloured orange.

NOAA scientists discover new species of gelatinous animal near Puerto Rico – CTV News

Published

 on


Scientists have discovered a new species of ctenophore, or comb jelly, near Puerto Rico.

The newly named Duobrachium sparksae was discovered two and a half miles below sea level by the National Oceanic and Atmospheric Administration Fisheries research team. It was found during an underwater expedition using a remotely operated vehicle in 2015 and filmed by a high-definition camera.

NOAA Fisheries scientists Mike Ford and Allen Collins spotted the ctenophore and recognized it as a new species. This is the first time NOAA scientists have identified a new species using only high-definition video, according to NOAA.

“The cameras on the Deep Discoverer robot are able to get high-resolution images and measure structures less than a millimeter. We don’t have the same microscopes as we would in a lab, but the video can give us enough information to understand the morphology in detail, such as the location of their reproductive parts and other aspects,” Collins said.

The scientists also said there was another unique quality to the discovery. During the expedition, they were not able to gather any samples, so the video evidence is all they have.

“Naming of organisms is guided by international code, but some changes have allowed descriptions of new species based on video — certainly when species are rare and when collection is impossible,” Ford said. “When we made these observations, we were 4,000 metres down, using a remote vehicle, and we did not have the capabilities to take a sample.”

There are between 100 and 150 species of comb jellies, and despite their name, they are not related to jellyfish at all, according to the NOAA. The species is carnivorous, and many are highly efficient predators that eat small arthropods and many kinds of larvae.

The researchers said that there did not initially get a long look at the animal, so there is still a lot about this new species that they do not know yet. Their findings were recently published in the journal Plankton and Benthos Research.

“We’re not sure of their role in the ecosystem yet,” Ford said.

“We can consider that it serves similar roles to other ctenophores near the ocean floor and it also has some similarities to other ctenophores in open ocean areas,” he said.

The videos are now part of the Smithsonian National Museum of Natural History Collection and publicly accessible.
