At the edge of the galactic black hole

Posted by in categories: climatology, cosmology, physics

A team of researchers – including the Max Planck Institute for Extraterrestrial Physics in Garching – have gained astounding insights into the galactic centre: The astronomers have spotted gaseous clouds which are spinning around the assumed black hole at the heart of the Milky Way at a speed of around 30 percent of the speed of light. The gas is moving in a circular orbit outside the innermost stable path and can be identified through radiation bursts in the infrared range. This discovery was made possible by the Gravity Instrument, which combines the light of all four eight-metre mirrors of the Very Large Telescope at the European Southern Observatory (ESO). Thanks to this technology, which is called interferometry, Gravity generates the power of a virtual telescope with an effective diameter of 130 metres.

This unusually compact object sits right in the middle of the Milky Way and generates radio emissions: Astronomers call it Sagittarius A*. It is highly probable that this is a black hole with the mass of approx. four million suns. But this is by no means certain, and scientists are always devising new tests to support this thesis. Researchers have now used the Gravity Instrument to take a close look at the edges of the alleged black hole.

According to this theory, the electrons in the gas approaching the event horizon should speed up and therefore increase in brightness. The region of only a few light hours around the black hole is very chaotic, in a similar way to thunderstorms on Earth or radiation bursts on the Sun. Magnetic fields also play a part here, because the gas conducts electricity making it a plasma. The latter should ultimately show up as a flickering “hot spot” circling the black hole on the final stable path.

Scientists map Mars’ global wind patterns for the first time

Posted by in categories: climatology, space travel

Today, a paper published in Science documents for the first time the global wind circulation patterns in the upper atmosphere of a planet, 120 to 300 kilometers above the surface. The findings are based on local observations, rather than indirect measurements, unlike many prior measurements taken on Earth’s upper atmosphere. But it didn’t happen on Earth: it happened on Mars. On top of that, all the data came from an instrument and a spacecraft that weren’t originally designed to collect wind measurements.

In 2016, Mehdi Benna and his colleagues proposed to the Mars Atmosphere and Volatile EvolutioN (MAVEN) project team that they remotely reprogram the MAVEN spacecraft and its Natural Gas and Ion Mass Spectrometer (NGIMS) instrument to do a unique experiment. They wanted to see if parts of the instrument that were normally stationary could “swing back and forth like a windshield wiper fast enough,” to enable the tool to gather a new kind of data.

Initially, the MAVEN project team was reluctant to implement the modifications Benna and his colleagues requested. After all, MAVEN and NGIMS had been orbiting Mars since 2013, and they were working quite well collecting information about the composition of the Mars . Why put all that at risk? Benna and his colleagues argued that this project would collect new kinds of data that could shape our understanding of the upper atmosphere on Mars, inform similar studies on Earth, and help us better understand planetary climate.

ISS Sees Thunderstorm Beaming Electromagnetic Pulse Into Space, Producing Gamma Rays and ‘Elves’

Posted by in categories: climatology, space

O…O.


At 8:01 p.m. on October 10, 2018, a bolt of lightning flashed inside of a storm cloud just east of the Indonesian island of Sulawesi. The International Space Station was passing overhead at the time, and a suite of instruments observed as the bolt produced a flash of gamma radiation—and, simultaneously, emitted a glowing ring of ultraviolet and visible light in the topmost layer of the atmosphere.

Scientists today are presenting the results of this observation, the first to capture both a terrestrial gamma ray flash, or TGF, and the visible-light component of an Elve, a dim disk of ionospheric radiation. This observation provides more evidence for the connection between lightning, the radiation produced by storms, and electromagnetic phenomena at the top of the atmosphere, while illustrating more of the wild radioactive curiosities that weather can generate.

Scientists Are Contemplating a 1,000-Year Space Mission to Save Humanity

VR and Interstellar Travel

Crew members in route to a distant planet may best be accommodated by full immersion VR. The actual spaceship could be reduced to a relatively simple, small, well-shielded vehicle. Inside the crew’s biological material could be supported by a simplified nutrition, waste and maintenance system. Their minds could inhabit a fully immersive VR environment that would provide them with all the luxuries of vast, diverse spaces and experiences — complete with simulated gravity, simulated pleasant nature-like and artificial environments, and simulated meals.

They could also engage in simulating the type of society they intend to build once they arrive in their new physical environment, using similar constraints to the ones they will encounter. This could allow many years for actual human experiences to test and refine what they will build and how they will interact in their new home.

Massive Dust Towers Are Linked To Mars’ Ancient Water Loss, Says NASA

Posted by in categories: climatology, space

Between the solar wind stripping its atmosphere and these horrific dust towers bleeding its water into space, Mars may not have ever had a chance at a stable climate.


NASA reports that these are the result of observations by NASA’s Mars Reconnaissance Orbiter’s heat-sensing Mars climate sounder instrument which can easily penetrate this dusty haze.

We’re not yet able to understand how much these towers contributed to Mars’ past water loss, David Kass, a planetary scientist at NASA Jet Propulsion laboratory and the Mars Climate Sounder instrument’s principal investigator, told me by phone. But they are telling us that the simple extrapolations that we were doing before to explain Mars’ water loss has limitations, he says.
