Scientists Propose Permanent Human Habitat Built Orbiting Ceres

Posted by in categories: habitats, space

Would you like to live on a space station? 😃


If that sounds familiar to fans of the popular sci-fi book and TV series “The Expanse,” that’s because in that fictional universe, Ceres Station plays a pivotal role as one of humanity’s first human off-world colonies. In the series, however, the space rock itself was spun up to create a crewed habitat on its surface with artificial gravity.

In a paper uploaded to the prewrite repository arXiv this week, the team argues that Ceres would be prime real estate because it has nitrogen, which could enable the creation of an Earth-like atmosphere.

When Galaxies Collide: Hubble Showcases 6 Magnificent Galaxy Mergers

Posted by in categories: evolution, space

To celebrate a new year, the NASA /ESA Hubble Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key aspect of galaxy evolution and are among the most spectacular events in the lifetime of a galaxy.

It is during rare merging events that galaxies undergo dramatic changes in their appearance and in their stellar content. These systems are excellent laboratories to trace the formation of star clusters under extreme physical conditions.

The Milky Way typically forms star clusters with masses that are 10 thousand times the mass of our Sun. This doesn’t compare to the masses of the star clusters forming in colliding galaxies, which can reach millions of times the mass of our Sun.

NASA to launch SphereX telescope into space in 2024

Posted by in category: space

During its two-year mission, SphereX will map the entire sky four times, creating an enormous database of stars, galaxies, nebulas and other celestial objects.

The space telescope will be NASA’s first to build a full-sky spectroscopy map in near-infrared, and it will observe a total of 102 near-infrared colours.

The Giant Magellan Telescope Will Revolutionize Our View and Understanding of the Universe

Posted by in category: space

The Giant Magellan Telescope will be one of the few super giant earth-based telescopes that promises to revolutionize our view and understanding of the universe. It will be constructed at the Las Campanas Observatory in Chile. Commissioning of the telescope is scheduled to begin in 2021.

The GMT is a segmented mirror telescope that employs seven of today’s largest stiff monolithic mirrors as segments. Six off-axis 8.4 meter segments surround a central on-axis segment, forming a single optical surface 24.5 meters in diameter, with a total collecting area of 368 square meters. Harvard University and the Smithsonian Institution are both members of the GMT project, which also includes Astronomy Australia Ltd., the Australian National University, the Carnegie Institution for Science, the Korea Astronomy and Space Science Institute, the São Paulo Research Foundation, the University of Texas at Austin, Texas A&M University, the University of Arizona, and the University of Chicago.

Making methane on Mars

Posted by in categories: Elon Musk, energy, space

“The process of creating methane-based fuel has been theorized before, initially by Elon Musk and Space X. It utilized a solar infrastructure to generate electricity, resulting in the electrolysis of carbon dioxide, which, when mixed with water from the ice found on Mars, produces methane. This process, known as the Sabatier process, is used on the International Space Station to produce breathable oxygen from water. One of the main issues with the Sabatier process is that it is a two-stage procedure requiring large faculties to operate efficiently. The method developed by Xin and his team will use anatomically dispersed zinc to act as a synthetic enzyme, catalyzing the carbon dioxide and initializing the process. This will require much less space and can efficiently produce methane using materials and under conditions similar to those found on the surface of Mars.”


Among the many challenges with a Mars voyage, one of the most pressing is: How can you get enough fuel for the spacecraft to fly back to Earth?

Houlin Xin, an assistant professor in physics & astronomy, may have found a solution.

Source of Sunquakes is Submerged beneath Solar Surface, Study Shows

Posted by in category: space

Ultra-impulsive acoustic emission from a solar flare recently detected by NASA’s Solar Dynamics Observatory (SDO) indicated submersion of its source beneath the active region that hosted the flare.

Exoplanet Found

Posted by in category: space

By Hubble Resembles Reputed “Planet Nine” in Our Solar System.


Astronomers confirm bound orbit for planet far from its star, showing that far-flung planets exist.

Astronomers are still searching for a hypothetical “Planet Nine” in the distant reaches of our solar system, but an exoplanet 336 light years from Earth is looking more and more like the Planet Nine of its star system.

NASA’s first mission to the Trojan asteroids integrates its second scientific instrument

Posted by in categories: evolution, space

NASA’s Lucy mission is one step closer to launch as L’TES, the Lucy Thermal Emission Spectrometer, has been successfully integrated on to the spacecraft.

“Having two of the three instruments integrated onto the is an exciting milestone,” said Donya Douglas-Bradshaw, Lucy project manager from NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The L’TES team is to be commended for their true dedication and determination.”

Lucy will be the first space mission to study the Trojan asteroids, leftover building blocks of the Solar System’s outer planets orbiting the Sun at the distance of Jupiter. The mission takes its name from the fossilized human ancestor (called “Lucy” by her discoverers) whose skeleton provided unique insight into humanity’s evolution. Likewise, the Lucy mission will revolutionize our knowledge of planetary origins and the birth of our solar system more than 4 billion years ago.

An eye on experiments that make quantum mechanics visible

Posted by in categories: particle physics, quantum physics, space

The human eye is a surprisingly good photon detector. What can it spy of the line between the quantum and classical worlds?


I spent a lot of time in the dark in graduate school. Not just because I was learning the field of quantum optics – where we usually deal with one particle of light or photon at a time – but because my research used my own eyes as a measurement tool. I was studying how humans perceive the smallest amounts of light, and I was the first test subject every time.

I conducted these experiments in a closet-sized room on the eighth floor of the psychology department at the University of Illinois, working alongside my graduate advisor, Paul Kwiat, and psychologist Ranxiao Frances Wang. The space was equipped with special blackout curtains and a sealed door to achieve total darkness. For six years, I spent countless hours in that room, sitting in an uncomfortable chair with my head supported in a chin rest, focusing on dim, red crosshairs, and waiting for tiny flashes delivered by the most precise light source ever built for human vision research. My goal was to quantify how I (and other volunteer observers) perceived flashes of light from a few hundred photons down to just one photon.

Astronomers Create Radio Map of Perseus Galaxy Cluster

Posted by in category: space

Astronomers using NSF’s Karl G. Jansky Very Large Array have produced a high-resolution map of the Perseus cluster, a collection of thousands of galaxies approximately 240 million light-years from Earth.
