Asteroids, UFOs, and solar eclipses were among the most talked about topics this week, with giant comet Bernardinelli-Bernstein also in the spotlight. If you missed any of this week’s astronomy and space exploration news, check out our roundup below.

Unfortunately, this year’s first solar eclipse will not be visible in Brazil. It will take place on April 30 and will be partial, but only residents of Argentina, Uruguay, Chile and Bolivia will be able to enjoy it. Brazilians will be able to find the moon “walking” next to the sun all day, but remember: never look directly at our star.

Those who wish to observe the moon’s path closer to the sun should use a welding mask lens No. 14. If you have any instrument, such as binoculars or a telescope, you must use the appropriate filters on the objective lens.
British tabloid the sun I asked the US government for a copy of all files, reports, or videos related to the Advanced Aviation Hazard Identification Program (AATIP), a classified US Department of Defense initiative active from 2007 to 2012. From the Freedom of Information (FOIA).
According to the car, thousands of pages of documents obtained report on various biological effects on the human body. Among them are 300 “unpublished” cases of injuries that allegedly occurred after UFO encounters, from burns to health problems related to electromagnetic radiation. There are also cases of brain and nerve damage, heart palpitations, and headaches associated with such encounters.
It is important to note that object observers are reporting to the authorities, and these objects are not necessarily alien technology (UFO stands for “unidentified flying object”, including anything unknown made by humans). There are also reports of “unexplained pregnancies”, “apparent abductions”, paralysis, experiences of telepathic perception, teleportation, and soaring.

It appears that the famous 1I/ʻOumuamua was not the first interstellar object to appear near Earth in recent times. At least that’s what Amir Siraj and Abraham “Avi” Loeb say in a new study that analyzed ancient data from meteors that passed through our atmosphere. They found an object that crashed and fell into the sea in 2014. Its speed was out of line with any meteorite that originated in the solar system.
Although the original study article brings a high degree of certainty to its conclusions, it has not been reviewed or published in any scientific journal yet, despite being published in the arXiv online repository in 2019. Now, data about the object has been released in A note from the US Space Command (USSC) appears to “confirm” the research.
Neptune is a planet located about 4.5 billion km from the Sun; So it is very cool. Its average temperature is -220°C and its seasons last about 40 Earth years. It is currently summer in the southern hemisphere of the planet, but the temperatures there have behaved very strangely in recent years.
Through infrared observation data over the past 17 years, astronomers have detected a decrease in the global temperature of the ice giant, and rapid warming in the Antarctic. This warming is strange, because Neptune has not yet reached the middle of the Australian summer. Rather than showing a gradual increase across the entire Southern Hemisphere, it gradually cooled, while the Antarctic warmed faster than expected.
So far, no one has been able to explain the mechanisms behind these climate dynamics on Neptune.
Hubble data reveal that the nucleus of Comet Bernardinelli-Bernstein (or C/2014 UN271) will be about 130 km in diameter. If this measurement is confirmed, the object will officially be 50 times larger than the nucleus of most known comets.
The giant comet also has a mass of 500 trillion tons; That is, it is a hundred thousand times larger than “ordinary” comets. Although it is the only one of its kind observed so far, scientists believe it is just the “tip of the iceberg,” meaning that there must have been thousands of other giant statues frozen in the Oort Cloud, a region in the outer reaches of the Solar System.
China is launching a space observatory called Terra 2.0, which will search for planets under the same conditions as ours. For this, candidates will have to meet a number of requirements, such as orbiting a sun-like star, being in a habitable zone, and of course it must be rocky. For this, the satellite will be equipped with seven telescopes.
Six of these instruments will work together to detect 1.2 million stars in an area of the sky of 500 square degrees. Its seventh instrument will be a telescope that uses the micro-lens of gravity to search for exoplanets as far from their stars as Neptune is from the sun. Its target will be the center of the Milky Way, and if successful, it will be the first accurate gravitational telescope operating in space.
The Messaging Extraterrestrial Intelligence (METI) group wants to pass on scientific data and even music samples to potential extraterrestrials. The transmission will consist of short pulses, initially only so that recipients of the message can recognize it as something artificial. Then there will be simple enumerations, after which data will be translated into details of the periodic table and representations of atoms.
It will include music samples Poem 1. A poem for the evangelist of God.

The target is the TRAPPIST-1 system, and it’s close enough that we’ll have an answer in 80 years — if there was intelligent life out there that could decode the message and transmit something back.
I will never tire of sunrise on Mars. ☀️ Every morning, that distant point climbs higher in the sky, giving me the energy for another round of listening to the bangs under my feet. https://t.co/QB4uVOBLAP pic.twitter.com/61dZe75k2I

NASA has published on social media a series of images taken by NASA’s Insight spacecraft, revealing the sunrise on the Red Planet. Several images taken by the spacecraft have been combined into an animation to present the experience of watching the dawn on Mars, with inhospitable beauty that does not exist on Earth.
The consequences of the Russian invasion of Ukraine continue to affect plans for space exploration. The European Space Agency (ESA) this week suspended its cooperation with the Russian Space Agency (Rosmos) in the development of three missions to the Moon, with the Luna-25 probe, Luna-27 and the Luna-26 orbiter.
With this, the European Space Agency will have to rely on NASA and private companies to carry out its next missions to the Moon. The European Agency also announced its support for the initiatives that will be part of the package of activities that the Agency will present at the ministerial meeting to be held at the end of the year.
