NASA’s Hubble Space Telescope first discovered a rogue black hole

NASA’s Hubble robotic observatory in low Earth orbit has provided the first direct evidence of a lone black hole drifting through interstellar space by measuring its mass and precise location for the first time. Until now, the masses of black holes have been determined indirectly, relying on their interaction with companions in binary systems or with stars in the cores of galaxies.

NASA's Hubble Space Telescope first discovered a rogue black hole

Hubble made observations of the Sagittarius-Carina spiral arm of the Milky Way, which made it possible to detect a black hole passing through this arm at a distance of about 5 thousand light-years from Earth. At the time of its formation millions of years ago, this black hole was pushed by a supernova explosion due to an asymmetric release of gravitational waves, after which it went on a long flight through the entire galaxy. “Black holes roaming our galaxy are born from rare monstrous explosions of massive stars that make up less than one thousandth of the entire stellar population of the Milky Way, they are at least 20 times more massive than our Sun. These stars explode as supernovae, and the remnants of their cores collapse under the influence of gravity, shrink and turn into black holes. Since the explosion does not turn out to be perfectly symmetrical, the black hole can experience a push and fly due to recoil through the entire galaxy. ”describes the appearance of NASA’s rogue black holes.

Hubble is unable to photograph a black hole directly, as it absorbs all the light falling on it, however, the powerful gravity of these objects distorts the surrounding space, and the light coming from the background stars is bent and amplified in places when the black hole passes in front of them, which gives astronomers the opportunity to record its presence. This effect is called the microlensing effect and can be used to measure the mass of a rogue black hole.

Hubble observed the passage of a black hole in front of the stars for 270 days, but then it took scientists another six years to process all the data. Researchers now believe that it is a black hole, but the possibility remains that the object is a neutron star. The estimated mass of an invisible compact object is between 1.6 and 4.4 solar masses. If it ends up in the upper part of this mass range, then it should be considered a black hole, otherwise it will be just a neutron star. According to astronomers, the object still has a fairly large mass and moves through the Milky Way at a speed of over 160 thousand km / h.

The best selling portable console Steam Deck will become more affordable

The Steam Deck console will be available in large volumes soon.

Valve has published a message that it is increasing the production of the console, more than doubling it!

It is unclear whether this will be enough to meet demand, since the company initially accepted a lot of orders for the console, and now it is very false to buy it. But such a significant increase in production volumes should have a positive impact on the availability and prices from resellers.

The company also announced that it has just completed deliveries of set-top boxes that were booked in the second quarter, and will begin accepting pre-orders for the third on June 30th. However, delivery on the site is still indicated no earlier than October.

7000 for 64 cores up to 45GHz AMD Threadripper 5000WX

At first there were rumors about this, then AMD officially confirmed everything: the powerful AMD Threadripper 5000WX processors will go on sale and become available to everyone. As it turned out, the CPU is already available in China.

The official start of sales is in July, at the same time the recommended retail prices will be announced. In the meantime, sellers are asking for Threadripper 5000WX much more than what they asked for their predecessors. Thus, the 64-core Threadripper 5995WX is offered for $7,030, while the official cost of the Threadripper 3995WX is $5,850. The 32-core Threadripper 5975WX is priced at $3,590, while its predecessor, the Threadripper 3975WX, is officially listed at $2,750. The Threadripper 5965WX is also available in China for the equivalent of $2,570.

The 16-core 5955WX and the 12-core 5945WX were left behind. Maybe they won’t go to retail at all.

At the moment, the reasons for the rise in price are not reported. However, it is possible that this was influenced by the expected increase in electricity prices. According to Bloomberg, about 22,000 industrial enterprises will buy electricity at a 15% higher price. This will lead to an increase in the cost of the final product.

It is TSMC that manufactures processors for Apple, Qualcomm AMD, Nvidia, and so on. thus, price increases will affect all segments of electronics – smartphones, game consoles, PCs, servers, and so on.
