In early August, unknown hackers attacked the control system of the Gemini North telescope in Chile.
Now work on the world’s largest telescopes is paralyzed. Hackers have been stubbornly attacking astronomers’ main telescope command systems for several days, and the attacks are still ongoing. The hackers make no demands, and no one has been held responsible for the attacks. It seems that the scientists have obtained some valuable data, and someone wants to intervene in further research.
It all started in early August when unknown assailants attacked the control system of the Gemini North telescope in Chile. And they tried to make the tube, which weighed tons, spin quickly and randomly. The telescope was supposed to destroy itself. But the operators quickly disconnected the device from the outside world.
Astronomers first thought the hacker attack was a mistake, assuming the attackers were targeting a bank or military facility, and didn’t even realize they had hit the telescope. Only brief public information was reported to the police about the incident.
But the unknown attacks intensified. Now all the large telescopes stationed in Hawaii and Chile have been disconnected from the network.
It is mentioned that very large telescopes are not built anywhere, but in places with an ideal astronomical climate, that is, there must be many clear nights, few winds, and calm atmosphere. There are only a few places on Earth where it would make sense to build a multi-billion dollar mega pipeline, and those places are primarily Hawaii and Chile. Of course, you could put your telescope anywhere, but it wouldn’t be of scientific value.
So the globe has become “blind”: no one looks into space. The tragedy is that many observations can only be achieved now because the celestial phenomena will not wait for you and will not repeat their offerings for you. Hundreds of scientific research projects have been thwarted and suspended.
Digital Tips : Tricks that can save hours of mobile battery life on Android phones!
Some little-known settings can provide a significant increase in the battery life of Android devices.
Kewen Charon, of technology repair company BackMarket, said errors ranged from using always-on screens to failing to adjust screen brightness.
Using Wi-Fi to determine location instead of GPS can also increase battery life, as can Android settings designed to turn off background apps.
Always disable display
Charon warned that your smartphone screen is the most power-hungry part of your device.
Charon said: The “always on” feature on “Android” devices allows users to see information, such as the time, without having to fully activate their phone.
However, with the Always On display enabled, you can see an additional battery drain of up to 1.5% per hour on your phone.
Turning it off may vary slightly depending on the device, but try setting the time in Settings > Display & Brightness > and Always On.
Turn on adaptive brightness
Turning on automatic or adaptive brightness settings, Charon said, can also help your battery last longer.
To do this, go to Settings > Display > and turn on Auto Screen Brightness or Adaptive Brightness.
“Dimming your device’s brightness to about 50% can also help conserve battery life, but make sure you don’t strain your eyes to read the dim screen,” Charon said.
Switching to dark mode can also reduce eye strain in low-light conditions, which is especially important for OLED screens.
Use Wi-Fi instead of GPS to locate
Charon said the little-known setting allows you to use Wi-Fi and Bluetooth for location rather than battery-draining GPS.
“When location services are turned on, your Android device is constantly communicating with satellites and other data sources to determine your exact location. This activity can drain your battery significantly,” said Charon. Select Battery Saver mode to use Wi-Fi and mobile networks for location detection instead of power-draining GPS.
To enable the battery saver setting on most Android devices, open the Settings app, select Battery, and tap Battery saver.
“When you enable the battery saving setting, you may notice that your phone will automatically switch to a dark theme, some visual effects and features may become limited, and apps may take longer to load,” Charron said. However, this setting will help increase battery life.
Use adaptive battery to turn off apps
Charon said that running apps you don’t use often in the background can drain battery life.
But a setting in the Android menus allows your device to turn off apps you don’t use often.
“The Adaptive Battery setting in Android allows your device to learn about your app usage and optimize your battery in line with your behavior,” Charon said. Enabling this setting for Android devices may be a little different, but try tapping Settings > Battery and turning on Adaptive Battery.
Don’t let your battery run out – or “overcharge” it
Charon warned that leaving your phone plugged in quickly reduces battery life.
Instead, you should aim to keep your charge level between 20-80%.
To avoid overcharging your phone, which will affect the overall performance and health of the battery, try using the Battery Care feature. Tap Settings > Battery > then turn on Battery Care to enable this feature. For other devices, the operation of this setting may be slightly different. Try Tap Settings > Battery > Battery Usage, then tap Optimized.
