Seeding the Stars

Posted by in categories: engineering, environmental, media & arts, space

The galaxy is a vast place with billions of potential new worlds for humanity to colonize, but interstellar space is so enormous that reaching even the nearest stars and planets by spaceship would take decades at best, and maybe many centuries. Even on arrival terraforming those barren planets would take just as long.

Two options for overcoming the immensity of space and time are the Seed Ship and the Data Ship, automated vessels able to colonize the worlds for us. We will examine those today, their advantages, limitations, and misconceptions, and variations of them we might use to seed the stars.

Inexplicable Flying Fox found in Hydra Galaxy Cluster

Posted by in category: space

High sensitivity radio observations have discovered a cloud of magnetized plasma in the Hydra galaxy cluster. The odd location and shape of this plasma defy all conventional explanations. Dubbed the Flying Fox based on its silhouette, this plasma will remain a mystery until additional observations can provide more insight.

A team led by Kohei Kurahara at the National Astronomical Observatory of Japan analyzed observations from the Giant Metrewave Radio Telescope (GMRT) targeting the Hydra galaxy cluster, located over 100 million light years away in the direction of the constellation Hydra.

By applying recent analysis techniques to the GMRT (Giant Metrewave Radio Telescope) data archive, the team was able to discover a cloud of magnetized plasma shaped like a flying fox which has never been reported before.

Scientists discover hidden oasis of life underneath world’s driest desert

Posted by in categories: biological, habitats, space, sustainability

POTSDAM, Germany — One of the most lifeless places on Earth is actually hiding an underground biosphere teeming with microscopic life! Researchers have unearthed this amazing oasis under Chile’s Atacama Desert. The findings not only change our view of life on Earth, but they might prove that there is still life under the soil of dead alien worlds like Mars!

Despite being renowned as the driest desert on Earth, with some regions going decades or even centuries without a drop of rain, researchers from Germany discovered hardy communities of microorganisms that have managed to carve out habitats deep below the desert floor. Down here, totally isolated from the surface world, microscopic life finds a way to eke out an existence against all odds.

Study author Dirk Wagner and the team from the GFZ German Research Centre for Geosciences explain that they detected signs of potentially viable microbial ecosystems as far as 13 feet underground. This remarkable discovery is upending our understanding of desert biodiversity, demonstrating that life can persist in even the most extreme subterranean environments on Earth.

Japan’s mini space-based solar power plant to beam energy home by 2025

Posted by in categories: solar power, space, sustainability

The mission is part of a project called OHISAMA (Japanese for Sun), which is on track for launch in 2025.

Japan is gearing up to test its space-based solar power station next year.


An adviser from Japan Space Systems, Koichi Ijichi, shared details about the plans of the mini space-based solar power plant.

Some White Dwarfs Might be Older than Previously Thought

Posted by in categories: energy, physics, space

More than 97% of the stars in our Galaxy will end their lives with a whimper—slowly cooling as stellar remnants known as white dwarfs. The cooling of white dwarfs follows a pattern that was thought to be so predictable that the temperatures of white dwarfs are used to determine the age of surrounding stars. New findings, however, indicate this pattern may need revision [1]. Predictions made by Antoine Bédard of the University of Warwick, UK, and his colleagues now indicate that some white dwarfs may undergo a process that “reinvigorates” the stars, significantly slowing down the cooling process. That change could alter the calculated ages of white dwarfs by billions of years.

When a small star (one with a mass 8 times or less that of the Sun) runs out of nuclear fuel, it sheds its outer layers to form a planetary nebula. The core of the star then collapses into a white dwarf. Producing no heat, white dwarfs spend their existences radiating their remaining energy into space, cooling and solidifying from the inside out. Or so astrophysicists thought.

In 2019, this model was disrupted by astronomers analyzing data from the European Space Agency’s Gaia mission. The researchers identified a previously unknown population of white dwarfs within the Milky Way with anomalous properties [2]. As stars age, their velocities increase with respect to nearby stars because of repeated gravitational interactions with those stars. The newly identified white dwarfs, dubbed the Q branch, have much higher average velocities than models indicate they should have based on their temperatures, a finding that suggests that the Q-branch white dwarfs are older than previously thought. Some process is slowing down the cooling.

Revealing Io: Juno Mission Unveils Stunning Features of Jupiter’s Moon

Posted by in category: space

“Io is simply littered with volcanoes, and we caught a few of them in action,” said Dr. Scott Bolton, who is the principal investigator of Juno. “We also got some great close-ups and other data on a 200-kilometer-long (127-mile-long) lava lake called Loki Patera. There is amazing detail showing these crazy islands embedded in the middle of a potentially magma lake rimmed with hot lava. The specular reflection our instruments recorded of the lake suggests parts of Io’s surface are as smooth as glass, reminiscent of volcanically created obsidian glass on Earth.”

Loki Patera was first imaged by NASA’s Voyager 1 in 1979, revealing a very active surface and the most active of the four Galilean moons. The reason for Io’s immense volcanic activity is due to tidal heating, which occurs from Io’s somewhat elliptical orbit around the much larger Jupiter, which causes Io to orbit closer and farther away to Jupiter throughout its small orbit. This results in Jupiter’s massive gravity stretching and expanding the small moon, leading to friction within Io’s core, and eventually to heat. Since this process is ongoing, this means Io has been volcanically active for eons and could be volcanically active eons from now, as well.

Scientists Say Something Seems to Have Broken Off the Moon at This Crater

Posted by in category: space

A team of astronomers believes the near-Earth asteroid Kamo’oalewa, a space rock between 130 and 328 feet in diameter, was once part of the Moon.

More specifically, a research team led by Tsinghua University astronomer Yifei Jiao suggests the rock was gouged from a geological feature on the far side of the Moon called the Giordano Bruno crater, named after a 16th-century Italian cosmological theorist.

“We have explored the processes for impact-induced lunar fragments migrating into Earth co-orbital space and presented support for Kamo’oalewa’s possible origin from the formation of the Giordano Bruno crater a few million years ago,” the researchers write in their paper published in the journal Nature Astronomy last week.
