Space life – Where are they? (4/4)
We know that the probability that life can arise is not zero. We are the proof of that. But researchers have long tried to calculate whether it could have arisen elsewhere. One of the reasons many astronomers believe there is other life in the universe is the discovery of all the thousands of Earth-like exoplanets…
Space Life – The Shift and the Mysterious Signal (1/4)
In 2019, a telescope in Australia picks up a mysterious signal in the direction of our nearest neighbor star. When the astronomers study the frequencies, it appears to come from technology. The discovery creates headlines when it comes out that it may be about extraterrestrial contact. In recent years, interest in life in space has…
Everything, including black holes, eventually evaporates: Explore
The study was published June 2 in “Physical Review Letters,” the flagship journal of the American Physical Society (APS). This radiation is also caused by gravity and the curvature of space-time. This means that all large objects in the universe, such as stellar remnants, will eventually disappear. Spiral In this new study, Radboud University researchers…
It’s going to be a beautiful aurora night
As reported by mbl.is, clear skies and a strong solar wind are set to bring dazzling auroras over Iceland tonight. In a press release published today, Sævar Helgi Bragason, an educator and science communicator (editor of an astronomy website), predicts that the midnight lights will be enjoyed tonight. Sævar directs those interested to Icelandic […]…
The brightest planets in close conjunction
The two brightest planets, Venus and Jupiter, will be visible in the sky tonight. The planets will be very close to each other and as soon as the weather conditions allow it, you will be able to observe them even at low magnification, using a telescope or telescope. According to an article on the astronomy…
YLE: Finland is behind other Nordic countries in the recovery of tourism
Slow recovery is explained by unfamiliarity. “Only 20 percent of the respondents belonging to the target groups of our target market stated that they knew something about Finland. In Great Britain and the United States, familiarity was only 10 percent. Kristiina HietasaariThe director of Visit Finland told YLE on Wednesday. Finland also did not make…
Solar system estimated to be about 4.57 billion years old: Study
In a recent study published in the journal Nature Astronomy, researchers using isotopic analysis found that carbonate minerals from the asteroid crystallized in reactions with water, which initially accumulated on the asteroid as ice in the still-forming solar system and then warmed to liquid. They say that these carbonates formed very early – in the…
Sharper images of black holes can show if they are actually holes
The very first image of a black hole came three years ago. But now, through a major international collaboration, astronomers have presented the first image of a black hole that is much closer to us, in the heart of our galaxy, the Milky Way. Participants: Michael Lindqvist, astronomer at Chalmers and Onsala Space Observatory. Göran…
According to research, a new type of UV light makes indoor air as safe as outdoors
Disinfection of indoor air with remote UVC light is a new way to safely and effectively destroy airborne viruses in occupied spaces. Research has suggested that remote UVC light from ceiling-mounted lamps could be a highly effective passive technique to reduce the infectivity of airborne diseases and reduce the risk of a subsequent pandemic. “Far-UVC…
Astronomers map out a mysterious element in space, the study reveals
Ytterbium is one of the four elements in the periodic table, named after the Ytterby mine in the Stockholm archipelago. The element was first discovered in black gadolinite, first identified in the Ytterby mine in 1787. Ytterbium is interesting because it can have two different cosmic origins. Scientists believe that one half comes from heavy…
Astronomers are discovering a new planet around the nearest star in our solar system
The results of the study were published in the journal Astronomy and Astrophysics. A group of astronomers in Chile using the VLT telescope from the European Southern Observatory (ESO) has found evidence of another planet orbiting Proxima Centaur, the closest star in our solar system. “The discovery shows that our nearest star in our neighborhood…
Even dying stars can give birth to planets, astronomers suggest
The study was published in Astronomy & Astrophysics, where the discovery is described. In the study, astronomers suggested that even if the stars were close to death, some of them could still form planets. If this is confirmed, theories about planet formation will need to be adapted. Planets like Earth and all the other planets…
Potato stew? Life beyond Chips n Fries
By Pushpesh PantNew Delhi [India]January 4 (ANI): The potato has always been treated as a plebeian vegetable in India, but in many other countries it is the base that replaces cereals. Ever since tuber solanum tuberosum made its journey from the South American continent to the older world, chaperoned by Portuguese conquistadors, it has played…
The telescope tightens its sun visor – if it goes wrong, everything goes wrong
There are many small steps that should work when the telescope, after its narrow journey in an Ariane rocket, unfolds its various parts to reach its final shape in a few weeks. Then it should also have reached its place in space, 1.5 million kilometers into the solar system. How’s the telescope doing right now?…
Launch of the world’s largest space telescope – the countdown is underway
After years of delays, the Hubble Space Telescope’s successor will now be sent into space. Researchers have been working with the new so-called James Webb telescope for decades and some components have been partly developed by researchers here in Sweden. The hope is that the new space telescope will increase knowledge about the universe’s first…
Science for 100 billion on its way to space
The James Webb Telescope is supposed to give us a whole new picture of the universe, it is thought, and perhaps find traces of life on distant planets. But the launch and the journey through space are technical challenges on a whole new level. Hundreds of elements must work flawlessly for it to succeed, so…
A crater on Mars named after a town in Iceland
The International Astronomical Union Working Group on the Nomenclature of the Planetary System approved the name Flateyri for a crater on Mars. Flateyri is a town in the Westfjords. Icelandic astronomy expert Sævar Helgi Bragason, editor of the Stjörnufræðivefurinn website and director of the Seltjarnarnes astronomy society, explains that the person who proposed the name…
Astronomers are collaborating to create a new method for understanding the evolution of galaxies
As a result, a breakthrough study published in the Astrophysical Journal outlines their new method for elucidating star formation in a post-stellar galaxy using its cluster population. The approach uses age and mass estimates of the constellations to determine the intensity and velocity of the stellar eruption that prevented more stars from forming in the…

Babylonian mathematics is important every second
The mathematics of the Babylonians, however, differ a little from our own. They used 60 as the base number instead of 10. It has reportedly laid the foundation for our modern time reckoning. The people today are especially known for mastering the quadratic equations. That’s what Jesper Lützen, professor of mathematics at the University of…

Skåne [Sweden], 27 August (ANI): A research group at Lund University in Sweden has succeeded in following the evolution of a galaxy over an interval of 13.8 billion years using a supercomputer simulation. The study, published in the Monthly Notices of the Royal Astronomical Society, shows how young and chaotic galaxies mature over time into…
Astronomers find a break in one of the spiral arms of the Milky Way: NASA
This stretches for about 3,000 light-years and is the first large structure with a direction so dramatically different from the arm. NASA said astronomers have a rough idea of the size and shape of the Milky Way’s arms, but much is still unknown. “They can’t see the whole structure of our home galaxy because Earth…
