Scientists have shown the first image of a black hole in the center of the Milky Way

This is the second one to be photographed. The first was in 2019 in the galaxy Messier 87.

Scientists today revealed the first image of a black hole called Sagittarius A* – or SgrA* – at the center of our Milky Way galaxy. This is only the second one to be photographed. The first was in 2019 in the galaxy Messier 87.

This feat was achieved by the Event Horizon Telescope (EHT), which in 2019 also discovered

first photo the first black hole.

Sagittarius A* has a mass 4 million times that of our Sun and is located about 26,000 light-years – the distance light travels in a year – from Earth.

Black holes are extremely dense objects with such strong gravity that not even light can escape them. When reaching a black hole, its point – stars, planets, gas, dust and all forms of electromagnetic radiation – are swept away and disappear.

The scientists of the project were looking for a ring of light – superheated matter that circulates at high speed at the edge of the horizon – at the behest of the zone of darkness, which is a real black hole. This is known as the shadow or silhouette of a black hole.

The Milky Way is a spiral galaxy of which the solar system is a part. Seen from above or below, it resembles a rotating weather vane with the sun in one of the spiral arms and Sagittarius A* in the center.

A 2019 image of a supermassive black hole in a galaxy called Messier 87 or M87 shows a glowing red, yellow and white ring around its dark center. Black hole M87 is much further and more massive than Sagittarius A*, located about 54 million light-years from Earth.

The scientists noted that Sagittarius A*, despite being much closer to our solar system than M87, is harder to visualize.

The diameter of Sagittarius A* is about 17 times that of the Sun, which means that it is within the solar orbit of the planet Mercury. In contrast, M87’s diameter spans our entire solar system.

“Sagittarius A* is more than a thousand times less massive than the black hole in M87, but because it’s in our own galaxy, it’s much closer and should look a little bigger in the sky,” said EHT astronomer Lindy Blackburn. .

“However, the smaller size of the Sgr A* also means that it is about a thousand times faster than the M87.

Kerbal Space Program 2 now kicks off in early 2023

Kerbal Space Program 2 now kicks off in early 2023

The Kerbal 2 space program will remain on earth for some time to come. Developer Star Theory has delayed the release of the game until early 2023.

Creative director Nate Simpson explained on the project’s forums and in a video message that development of the space flight simulator has “enormous technological complexity” and the team needs more time to bring it to perfection. In the video posted below, Simpson clarifies by saying:

“We have also set very high quality standards. the game should [perform] for a wide range of vehicles. Graphics must be second to none. The universe should be rich and interesting to explore. We set ourselves an internal goal – to create an original and breathtaking experience.

Like its well-received predecessor, Kerbal Space Program 2 challenges players to manage a space program run by cute green astronauts to build rockets and other spacecraft for space exploration. The game uses realistic physics to allow players to perform realistic orbital maneuvers used to locate and land on celestial bodies. The sequel was first announced at Gamescom 2019 with a release window in 2020. Unfortunately, the COVID-19 pandemic delayed development and forced the team to aim for Fall 2021 to arrive later this year.

Kerbal Space Program 2 is aimed at PC at launch, with console versions coming later in the year.

Unfortunately, Kerbal isn’t the only major game that has been pushed back to 2023. We recently compiled a list of all the best games of 2022 to avoid this year, which you can read here.

See photos of the Blood Moon during the morning lunar eclipse - Science

Another lunar eclipse occurred this morning, resulting in the formation of a red moon and the formation of a supermoon, a phenomenon also known as the “moonflower”. It only partially obscures the Sun. This phenomenon has been observed in America, Europe and other regions of the globe. .

The phenomenon reached its peak around 4:11 am, when the Moon was completely in the cone of the Earth’s shadow. The total eclipse ended at 4:54 am. The moon came out of the shadow at 5:55, but the penumbra remained for another hour.

See images of the lunar eclipse in the gallery:

“Although completely in shadow, the Moon is still visible, but has a reddish and brownish color. In fact, during a lunar eclipse, the sun’s rays fall on the moon after crossing the Earth’s atmosphere, where they scatter and lose a large amount of blue and green light, ”the Lisbon Astronomical Observatory explained. During an eclipse, the moon was illuminated not with white, but with a reddish light. The moment of the Full Moon phase lasted only two minutes.

At 7:52 AM, the Moon completely emerged from the penumbra, returning to its usual hue, although it was already below the horizon.

According to the observatory, the next total lunar eclipse will occur on November 8, 2022.

Introduced in iOS A few years ago, the widget feature is now a new category of apps that have been captivating the youth in recent months and becoming a favorite for photo-sharing. These are services such as Locket and LiveIn that display contact photos on the home screen of a mobile phone.

New sharing apps have become Gen Z’s way of interacting online. Locket and LiveIn apps are not exclusive iPhone and also available for Android system. However, they have become popular among iOS device users, especially in the United States.

In general, these applications work quite simply. To send a picture, simply open the app, take a picture, and choose who to share it with. To view files sent by your friends, simply activate the widget on the home screen of your mobile device. In this way, you can follow updates from friends without having to view unwanted posts such as advertisements and other posts.

“It’s more or less what you do in Snapchat, but without having to open the app,” explained Jimmy Wells, a LiveIn user based in the US, according to a posting on technologist Olhar Digital’s website. These apps only became possible in 2020 when the widget feature was included in the Apple operating system. But this functionality has been around for over a decade on Android.
