Algae biofuel has unlimited supplies that is also regenerative in its supply chain. It can reproduce nearly indefinitely bringing infinite supplies instead of oil which is dependent on earth this could even be used in space.
After ExxonMobil walks away, algae biofuel gets another shot at success and the US Department of Energy is here for it.
A groundbreaking study conducted by a team of international scientists has unveiled unprecedented insights into the nature of the asteroid Ryugu and shed light on the composition of water-and carbon-rich small bodies in the solar system.
Asteroids like Ryugu are remnants of planetary embryos that never reached larger sizes, making them invaluable windows into materials that formed in the early solar system.
The study centered on laboratory measurements of the samples brought back to the Earth by the Hayabusa2 spacecraft in 2020.
A groundbreaking detection of an extremely energetic cosmic ray by the Telescope Array experiment raises questions about its source, as it points to a cosmic void, challenging current theories in cosmic ray origins and high-energy physics.
Discovery of an Exceptional Extraterrestrial Particle
Researchers involved in the Telescope Array experiment have announced the detection of an extraordinarily energetic cosmic ray. This particle, which originated beyond our galaxy, possesses an astounding energy level of over 240 exa-electron volts (EeV). Despite this remarkable find, its exact source remains elusive, as its arrival direction does not point to any known astronomical entities.

NASA has completed its first laser link with an in-orbit laser relay system, marking a significant advancement in space communication technology.
The successful demonstration of two-way laser communications on Dec. 5 between laser terminals in different orbits could provide a basis for faster communications between Earth and the moon or even beyond.
CAPE CANAVERAL, Fla. (AP) — An orange tabby cat named Taters stars in the first video transmitted by laser from deep space, stealing the show as he chases a red laser light.
The 15-second video was beamed to Earth from NASA’s Psyche spacecraft, 19 million miles (30 million kilometers) away. It took less than two minutes for the ultra high-definition video to reach Caltech’s Palomar Observatory, sent at the test system’s maximum rate of 267 megabits per second.
The video was loaded into Psyche’s laser communication experiment before the spacecraft blasted off to a rare metal asteroid in October. The mission team at NASA’s Jet Propulsion Laboratory in Pasadena, California, decided to feature an employee’s 3-year-old playful kitty.
In a groundbreaking experiment, NASA has successfully sent a 15-second, high-definition cat video over 19 million miles to Earth from space.
NASA has sent an ultra-high definition, 15-second-long cat video over 19 million miles (over 30 million km), the space agency said on Monday. This was not done for fun, though the video choice is undoubtedly some in-joke, but rather an experiment for its Deep Space Optical Communications. The video was beamed to Earth from its $1.2 billion Psyche asteroid probe launched in October 2023.

Just four days after arriving in Earth’s orbit, China’s Shenlong space plane has been observed releasing six enigmatic “wingmen.”
China’s Shenlong (meaning “Divine Dragon”) robotic space plane has something strange four days after it arrives in Earth’s orbit.
In an unexpected move, China’s Shenlong space plane has been observed deploying 6 ‘wingmen’ objects, some of which are chatting.
Could Earth end up with a runaway greenhouse effect like Venus someday, and what could this mean for finding life on exoplanets? This is something a recent study published in Astronomy & Astrophysics hopes to address as an international team of researchers used a 3D global climate model to investigate if Earth is destined to develop a runaway greenhouse effect like the planet Venus, which precious studies speculate was once much like Earth long ago. This study holds the potential to bring awareness of the long-term consequences of climate change and what steps can be taken to mitigate the effects.

“Until now, other key studies in climatology have focused solely on either the temperate state before the runaway, or either the inhabitable state post-runaway,” said Dr. Martin Turbet, who is a research scientist at CNRS laboratories of Paris and Bordeaux and a co-author on the study. “It is the first time a team has studied the transition itself with a 3D global climate model and has checked how the climate and the atmosphere evolve during that process.”
Kerry Vahala and collaborators from UC Santa Barbara have found a unique solution to an optics problem. When we last checked in with Caltech’s Kerry Vahala three years ago, his lab had recently reported the development of a new optical device called a turnkey frequency microcomb that has applications in digital communications, precision time keeping, spectroscopy, and even astronomy.
This device, fabricated on a silicon wafer, takes input laser light of one frequency and converts it into an evenly spaced set of many distinct frequencies that form a train of pulses whose length can be as short as 100 femtoseconds (quadrillionths of a second). (The comb in the name comes from the frequencies being spaced like the teeth of a hair comb.)
Now Vahala (BS ’80, MS ’81, PhD ’85), Caltech’s Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics and executive officer for applied physics and materials science, along with members of his research group and the group of John Bowers at UC Santa Barbara, have made a breakthrough in the way the short pulses form in an important new material called ultra-low-loss silicon nitride (ULL nitride), a compound formed of silicon and nitrogen.
