Starship Asterisk*

The observed increase in the thermal inertia of the soil as it approaches the equator suggests that a certain mechanism of transport and sorting of regolith, depending on the size or composition of particles and boulders, operates in the northern hemisphere of the asteroid.

One merger of neutron stars can create gold in the volume of 20 masses of our Moon, which means that even if there may be thousands of times more supernovae and planetary nebulae than mergers of neutron stars, the latter is the main source of elements with the highest atomic weight in the periodic t...

The new year 2021 will be the time of breaking new records in the probe's mission. The device will make four even closer passages near our star and pass two times near Venus. In addition, from January 12 to 23, 2021, the probe will pass the Sun from the side facing the Earth, which will allow joint ...

The peculiarity of carbonaceous chondrites is that, in fact, they are the remaining building blocks of the solar system. All the ingredients needed to understand how to create a habitable planet like Earth are here.

In the process of tidal heating, the gravitational pull of Jupiter's satellites and the planet itself stretches and squeezes the satellites enough to warm them. As a result, some of the icy moons are warm enough to house oceans of liquid water, and in the case of the rocky moon Io, tidal heating tur...

Traces of phosphine have been found in the atmosphere of Venus. It is a potential biomarker https://bit.ly/3wHXTWg

Is it Jupiter’s Great Red Spot which was noticed in the mid-1800’s?

Stars over 130 solar masses (which form helium stars over 65 solar masses) undergo "supernova pair instability" due to the explosive burning of oxygen, which completely destroys the star without leaving a black hole. Stars with a mass of more than 300 solar masses collapse and can form a b...

Each year, the energy production required for the probes drops by 4 watts. By 2025, it will fall to a critical level and will no longer be enough to communicate with the Earth. Then the scientists will turn off the devices on the Voyagers, but before that the specialists will establish a communicati...

It turned out that instead of phosphine in the clouds of Venus they found sulfur dioxide

Goddard's summer intern recently helped discover the first planet of the TESS mission, orbiting two stars, as part of another civilian science program called Planet Hunters TESS.

The gas halos of both galaxies have already collided, although the first stars of the participants in this cosmic accident will begin to converge in about four billion years.

This new theory explains why some of the smaller lakes near Titan's North Pole, such as Lake Winnipeg, have very steep edges above sea level.

Scientists have created a computer model of the solar system, which includes 100 thousand objects, mainly belonging to the Kuiper belt. The model showed that in a system without Jupiter, the likelihood of collisions of asteroids and comets with the Earth would not change. And if Jupiter had less mas...

Understanding how the moons affect each other is important. Ultimately, this may shed light on the evolution of the lunar system as a whole. Jupiter has about 80 satellites, the four largest of which are Io, Europa, Ganymede, and Callisto.

Another exoplanet with a clean atmosphere was discovered in 2018. Its scientific name is WASP-96b, the planet is hot enough and is classified by astrophysicists as "hot Saturn".

Previous estimates of the number of new ones ranged from 10 to 300 per year.

Astrophysicists attribute this to the fact that in its center it has an unusual star - SAO 244567. Earlier studies have shown that at first the temperature of this star rose sharply from less than 40 thousand to 108 thousand degrees Fahrenheit, and then began to fall and emit less ionizing radiation...

The Earth has a magnetic field, or magnetosphere, that prevents the atmosphere from escaping into space. Mars has a weak magnetic field, and, apparently, it could not hold water.

Such strong magnetic fields can actually repel some of the material spirally directed towards the black hole, helping it resist gravity.

Japanese scientists found bacteria in the lower stratosphere, where they survived despite solar radiation. Then scientists decided to test the ability of microorganisms to survive in space.

The sheer scale of the Solar System makes this a staggering challenge. We barely see things that pass close to Earth. If I recall correctly, we spotted a rogue asteroid a few years ago after it passed Earth.

https://prnt.sc/10uzpps If you take a close look at the photos taken by NASA's new rover, you will notice something very, very strange. Where do metal structures come from on Mars?

It is taught in school - the main elements of which the Sun consists are hydrogen (73%) and helium (25%). Other elements include iron, nickel, nitrogen, oxygen, sulfur, silicon, carbon, magnesium, calcium, chromium, neon.
