Curiosity's rear Hazcam recorded the shadow of the rover's rear in a 12-hour view toward the Gale Basin floor. Several factors caused several artifacts in the image, including a black spot, the sun's distorted appearance, and rows of white pixels extending from the sun. NASA/JPL-Caltech

The Envision mission will not have much fuel, so it is going to perform an atmospheric braking on Venus

  • No comments
The project's research director on behalf of the European Space Agency: "The flight on Ariane 6 will not allow all the extra propellant that would be necessary to lower the orbit. Instead we will slow ourselves down by making repeated passes through the upper atmosphere of Venus, lowering to 130 km from the face of the planet"

In addition to its intriguing internal structure (and strange phenomena like diamond rain!), scientists believe that Neptune played an important role in the formation of the solar system and that its composition includes large amounts of gas that was part of the prestellar nebula from which the solar system formed

"Boson clouds" may explain dark matter

In this paper the authors argue that dark matter can be composed of particles called scalar bosons. The Higgs boson is a scalar boson but because of its mass it is not a candidate to form the dark matter

Umuamua: Not said to be extraterrestrial, but Umuamua was probably not a nitrogen glacier

  • 5 תגובות
Prof. Avi Leib claimed following the discovery of the first bone that arrived clearly outside the solar system that it was an artificial bone; In early 2021, other scientists proposed the claim that it was a nitrogen glacier that broke away from a planet in formation in another solar system. Leib and his research partners published a response paper arguing that there is not enough nitrogen in the galaxy to sustain such objects. The debate continues.

It's too late for Umuamoa, but we can be ready for the next strange interstellar visitor if we want to. It is possible to design and build a spacecraft that will encounter such an object at short notice

The assessment is that most of them are misinterpretations of conventional events, for example flocks of birds or drones, military systems in a secret American experiment and the greatest fear is of superior technology developed by a foreign power

The precious metal-rich asteroid 16 Psyche may not be a solid lump of metal after all but a pile of rocks

  • No comments
The researchers based their work on previous observational data that showed the asteroid is primarily a mixture of three components: metal, low-iron pyroxene and carbonaceous chondrite. A laboratory experiment led the researchers to the conclusion that the density of the asteroid is low. A NASA spacecraft is expected to reach it by 2026
From the artist's illustration above, you can get an impression of how nearby objects will look to the NEO Surveyor. Their faint heat signatures will appear as a band of dots that appear in red in this image, for our convenience. That way they will look different from the stars in the background, which are painted blue in the picture. Hunting for near-infrared objects will also allow scientists to determine not only the location and orbit of the objects but also their size. And it is the size that determines the extent of their destruction if they hit the Earth. Image: NASA

When LIGO and Virgo observe more black star collisions, they may observe many small black stars. If that happens, we may have to examine this idea of ​​darker matter more carefully

Organic materials have been found on meteorites before, but Yabusa was the first time a sample of an "S-type" asteroid was observed to contain organic molecules. It even came directly from the source, and was not subjected to significant periods of time on Earth before being tested.

Interesting hints of Pluto's geology are revealed in this image taken by the New Horizons spacecraft on July 9, 2015 from a distance of 5.4 million kilometers from here. This annotated version of the image shows a large dark formation known as "The Whale" located on Pluto's equator, with a narrow band and elaborate polygons. In the lower part of the image is a photograph of Pluto, in which the area covered by the camera is highlighted, with the equator and the main longitude marked in bold. Photo: NASA-JHUAPL-SWRI
