The sky is not the limit | Earendel, solar storm, near-Earth asteroid e+

The discovery of the star Earendel, the most distant star ever observed by humanity, stirred not only the scientific community but also social networks. THE Nasa published the image obtained by the Hubble telescope and the news made the news. In fact, Earendel’s very name contributed to the star’s success, and we’ll explain why below.

Our upper atmosphere was also agitated; not by scientific discoveries but by the arrival of strong solar storms. Discover the most important news of the week in our weekly summary!

The farthest star astronomers have observed so far is called Earendel, or, if you prefer, WHL0137-LS. It lies 12.9 billion light-years away and the Hubble telescope could only identify it as an individual star in its galaxy thanks to the gravitational lens.

If you’re a fan of Tolkien’s works and you’re familiar with the name Earendel, it’s no wonder: the name means “morning star” in Old English, but was inspired by the character of Eärendila half-elf who appears in the silmarillion and in a song the Lord of the Rings.

Solar storms began hitting Earth on Thursday (31) and are expected to continue battering the planet this weekend. Although one of them is rated “strong”, none of them will have significant impacts on the infrastructure of power grids and satellites.

The events are the result of about 20 flares emitted from the Sun, most from a single sunspot. In total, astronomers recorded three visible clusters of Earth-facing spots. Geomagnetic storms can occur until April 3, providing Northern Lights.

Asteroid 2007 FF1 recorded on March 24, at a distance of around 11.6 million kilometers (Image: Reproduction/Virtual Telescope)

Asteroid 2007 FF1 made its closest approach to Earth this Friday (1st), at 6:35 p.m., without any risk of collision with our planet. The distance was 7.4 million kilometers, or about 19 times the average distance between Earth and the Moon.

This space rock has a diameter between 110 and 260 m and is part of the Apollo group of asteroids (a class whose orbits are located near the Earth). It is considered potentially dangerous for being in an area of ​​7.5 million km from Earth and having a luminosity greater than 100 m in diameter, but there is no chance of a collision this century.

Scientists still don’t know what happens to information from particles falling into a black hole (Image: Reproduction/Gr@v — Gravitation @ Aveiro University)

A new study offers a fascinating idea: information from particles in the universe could be the fifth state of matter. That is, matter could come in solid, liquid, gaseous, plasma, and informational form. For this, the information must have mass, which has not yet been proven.

Each particle in the universe stores a set of information that tells its story over billions of years. Among this information are spin and mass, neither of which is ever lost. If information has mass and is a state of matter, it could be that the universe’s own dark matter is information.

The similarities between Venus and Earth intrigue scientists (Image: Reproduction/ESA)

A NASA researcher had an unusual idea: wrap the planet Venus in a kind of giant shell to make its atmosphere conducive to life. The idea is to turn the planet into a place where astronauts can set foot and explore without putting their own lives in danger. To accomplish this feat, robotic probes would suck in the toxic atmosphere of Venus and store the oxygen for future colonists.

The captured carbon would be used to build huge T-shaped tiles to assemble the giant hull. The bad news is that it would take 72 trillion of these tiles to cover the entire planet, and it would take at least 200 years for Venus’ atmosphere to start transforming. Despite the difficulties, some scientists have already seen the proposal as something viable.

The study showed that Mercury has an electric current ring, which causes geomagnetic storms.

Mercury has geomagnetic storms similar to Earth, according to new studies. The planet has an electric current ring, formed by a field of electrically charged particles flowing down the side of the planet. When this current is disturbed by particles from the solar winds, a geomagnetic storm is created.

Unfortunately for any inhabitants of the planet’s past or future, Mercury’s magnetic field is weak and its geomagnetic storms do not create visible auroras. There, the only way to observe the phenomenon would be by X-ray and gamma-ray instruments.

Acoustic waves on the Sun spin 3 times faster than previously thought (Image: Reproduction/NYU Abu Dhabi)

One type of high frequency acoustic wave forms a pattern of swirling vortices on the surface of the Sun. The waves are retrograde, which means they move against the solar rotation and are three times faster than predicted by theory. There are three known mechanisms that could explain the effect (magnetism, gravity, or convection), but none of them shed light on the observed speed.

Scientists still don’t know why these waves are so fast, but they’re excited about the possibility of new discoveries about our Sun. It is that these phenomena can provide a lot of information about the interior of the star, which cannot be observed directly.

The probe of the Chinese Tianwen-1 mission recorded, in high resolution, intense dust storms on Mars. The Zhurong rover’s “selfies” also reveal a layer of dust accumulated on the equipment, which is not good news: excessive dust can affect the power supply.

Fortunately, the Chinese engineers have designed the panels in such a way as to compensate for the reduced efficiency in these cases.

On its first mission in 2022, the company Blue Origin took six tourists into suborbital space aboard the New Shepard vehicle. The launch took place on Thursday (31) at 10:59 a.m. and took the class approximately 107 km. The capsule was released after about three minutes and tourists were able to unbuckle their seat belts to revel in the feeling of weightlessness on board.

The capsule began its return to Earth at 11:02 a.m., decelerating using a parachute, and landed at 11:09 a.m.
