The image reveals the black hole at the center of Messier 87, a massive galaxy in the Virgo galaxy cluster.
Event Horizon Telescope
For the first time ever, an international collaboration of astronomers has captured an image of a black hole.

Unveiled at a National Science Foundation event today, the above image represents a historic achievement in imaging of one of the most extreme and hard-to-observe phenomena in our universe.
Perhaps the most impressive thing about this image is the international cooperation required to create it. Because
light cannot escape from a black hole
, radio telescopes need to be specially tuned to capture
light from the very edge of the event horizon
. The black hole chosen for observation was located in Messier 87, a galaxy 55 million light-years away.

To create a telescope array powerful enough to capture light from this distance, telescopes from all around the world were used in unison. A team of more than 200 astronomers in 20 different countries used eight telescopes to form the Event Horizon Telescope Array, including the
Atacama Large Millimeter/submillimeter Array (ALMA)
, a 66-telescope array in Chile, and the South Pole Telescope in Antarctica.
Many of the telescopes were not designed to collect this kind of data, so new hardware and software such as atomic clocks had to be installed at each site. When all the telescopes collected data together, they formed a virtual array the size of the Earth itself.
The South Pole Telescope is located in Antarctica, the most extreme location of the eight telescopes in the Event Horizon Telescope Array.
Junhan Kim, The University of Arizona
The power of the telescope array as a whole is incredible: It is equivalent of the ability to read the date on a quarter in Los Angeles while standing in Washington, D.C.
The process of linking together telescopes to collect the image was not guaranteed to succeed. It required “some very interesting cosmic coincidences,” according to Sheperd Doeleman, project director of the Event Horizon Telescope. Photons of light had to leave the horizon of the black hole, to travel 55 million light-years to Earth, to avoid being absorbed by water vapor in Earth’s atmosphere, and then be picked up against the background of the much larger Messier 87 galaxy surrounding the black hole.
Doleman described the experience of seeing the final image as one of “astonishment and wonder.” “I think any scientist in any field would know what that feeling is, to see something for the first time,” he said in a press conference. “It is a part of the universe that was off limits to us. When that happens, it is an extraordinary feeling.”
The image conformed to scientists’ predictions almost exactly. “I was a little stunned that it matched so closely the predictions that we had made,” said Avery Broderick, associate faculty members at the Perimeter Institute and the University of Waterloo. “We will be able to improve the precision with which we can probe the area, and we may find scientific surprises.”

Talk to AI every day? New research says it might signal depression
Study finds daily AI chatbot use tied to higher rates of moderate depressive symptoms in U.S. adults.
Spending time chatting with AI assistants like ChatGPT, Google Gemini, Microsoft Copilot, or similar systems might be more than just a tech habit. A new study published in JAMA Network Open suggests that people who use AI chatbots daily are more likely to report moderate depressive symptoms compared with those who interact with them less frequently. Researchers found a roughly 30% higher odds of at least moderate depression among regular users, though they are careful to emphasize that this link is an association, not proof that chatbot use causes depression.
This finding comes from a national survey of nearly 21,000 U.S. adults conducted in 2025, where participants detailed how often they interacted with generative AI tools and completed standard mental health questionnaires. Within that group, about 10% said they used AI daily, and 5% said they engaged with chatbots multiple times throughout the day. Those daily users showed higher rates of reported depressive symptoms and other negative emotional effects, such as anxiety and irritability.

You might actually be able to buy a Tesla robot in 2027
Elon Musk promises Optimus humanoid robots will go on sale by year’s end, if reliability and safety checks out
Tesla CEO Elon Musk has once again laid out an ambitious timeline for the company’s long-awaited humanoid robot, Optimus. Speaking at the World Economic Forum in Davos, Musk said Tesla plans to begin selling Optimus robots to the public by the end of 2027, assuming the machines reach the levels of reliability, safety, and functionality the company is targeting.
The comments follow a series of years-long development milestones. Optimus, which was originally unveiled as the Tesla Bot in 2021, has undergone multiple prototype iterations and has already been pressed into service handling simple tasks in Tesla factories. According to Musk, those internal deployments will expand in complexity later this year, helping prepare the robotics platform for broader use.

Blue Origin joins the satellite internet race with its 6 Tbps TeraWave network
The enterprise-focused network puts Blue Origin on a collision course with Starlink.
Jeff Bezos' Blue Origin is taking satellite internet to a whole new level with its newly announced network, TeraWave. Geared toward enterprise clients, data centers, and government customers rather than everyday consumers, the service promises data speeds of up to a staggering 6 Tbps.
According to the official announcement, Blue Origin plans to launch 5,280 low-Earth orbit satellites and 128 medium-Earth orbit satellites for the service, with the first ones set to deploy in late 2027. The low-Earth satellites will rely on RF connectivity and offer a max data transfer speed of 144 Gbps, while the medium-Earth satellites will use optical links to reach the publicized 6 Tbps speed. In comparison, SpaceX's Starlink maxes out at 400 Mbps at the moment, with future upgrades aiming for 1 Gbps.

# Seeing the unseeable: Astronomers capture historic first image of a black hole

For the first time ever, an international collaboration of astronomers has captured an image of a black hole.
Recommended Videos
Unveiled at a National Science Foundation event today, the above image represents a historic achievement in imaging of one of the most extreme and hard-to-observe phenomena in our universe.
Perhaps the most impressive thing about this image is the international cooperation required to create it. Because [light cannot escape from a black hole](https://www.digitaltrends.com/space/quiet-black-hole-alma/), radio telescopes need to be specially tuned to capture [light from the very edge of the event horizon](https://www.digitaltrends.com/cool-tech/black-holes-outburst-x-rays/). The black hole chosen for observation was located in Messier 87, a galaxy 55 million light-years away.

To create a telescope array powerful enough to capture light from this distance, telescopes from all around the world were used in unison. A team of more than 200 astronomers in 20 different countries used eight telescopes to form the Event Horizon Telescope Array, including the [Atacama Large Millimeter/submillimeter Array (ALMA)](https://www.digitaltrends.com/space/alma-planet-formation/), a 66-telescope array in Chile, and the South Pole Telescope in Antarctica.
Many of the telescopes were not designed to collect this kind of data, so new hardware and software such as atomic clocks had to be installed at each site. When all the telescopes collected data together, they formed a virtual array the size of the Earth itself.

The power of the telescope array as a whole is incredible: It is equivalent of the ability to read the date on a quarter in Los Angeles while standing in Washington, D.C.
The process of linking together telescopes to collect the image was not guaranteed to succeed. It required “some very interesting cosmic coincidences,” according to Sheperd Doeleman, project director of the Event Horizon Telescope. Photons of light had to leave the horizon of the black hole, to travel 55 million light-years to Earth, to avoid being absorbed by water vapor in Earth’s atmosphere, and then be picked up against the background of the much larger Messier 87 galaxy surrounding the black hole.
Doleman described the experience of seeing the final image as one of “astonishment and wonder.” “I think any scientist in any field would know what that feeling is, to see something for the first time,” he said in a press conference. “It is a part of the universe that was off limits to us. When that happens, it is an extraordinary feeling.”
The image conformed to scientists’ predictions almost exactly. “I was a little stunned that it matched so closely the predictions that we had made,” said Avery Broderick, associate faculty members at the Perimeter Institute and the University of Waterloo. “We will be able to improve the precision with which we can probe the area, and we may find scientific surprises.”

Talk to AI every day? New research says it might signal depression
Study finds daily AI chatbot use tied to higher rates of moderate depressive symptoms in U.S. adults.

Spending time chatting with AI assistants like ChatGPT, Google Gemini, Microsoft Copilot, or similar systems might be more than just a tech habit. A new study published in JAMA Network Open suggests that people who use AI chatbots daily are more likely to report moderate depressive symptoms compared with those who interact with them less frequently. Researchers found a roughly 30% higher odds of at least moderate depression among regular users, though they are careful to emphasize that this link is an association, not proof that chatbot use causes depression.
This finding comes from a national survey of nearly 21,000 U.S. adults conducted in 2025, where participants detailed how often they interacted with generative AI tools and completed standard mental health questionnaires. Within that group, about 10% said they used AI daily, and 5% said they engaged with chatbots multiple times throughout the day. Those daily users showed higher rates of reported depressive symptoms and other negative emotional effects, such as anxiety and irritability.

You might actually be able to buy a Tesla robot in 2027
Elon Musk promises Optimus humanoid robots will go on sale by year’s end, if reliability and safety checks out

Tesla CEO Elon Musk has once again laid out an ambitious timeline for the company’s long-awaited humanoid robot, Optimus. Speaking at the World Economic Forum in Davos, Musk said Tesla plans to begin selling Optimus robots to the public by the end of 2027, assuming the machines reach the levels of reliability, safety, and functionality the company is targeting.
The comments follow a series of years-long development milestones. Optimus, which was originally unveiled as the Tesla Bot in 2021, has undergone multiple prototype iterations and has already been pressed into service handling simple tasks in Tesla factories. According to Musk, those internal deployments will expand in complexity later this year, helping prepare the robotics platform for broader use.

Blue Origin joins the satellite internet race with its 6 Tbps TeraWave network
The enterprise-focused network puts Blue Origin on a collision course with Starlink.

Jeff Bezos' Blue Origin is taking satellite internet to a whole new level with its newly announced network, TeraWave. Geared toward enterprise clients, data centers, and government customers rather than everyday consumers, the service promises data speeds of up to a staggering 6 Tbps.
According to the official announcement, Blue Origin plans to launch 5,280 low-Earth orbit satellites and 128 medium-Earth orbit satellites for the service, with the first ones set to deploy in late 2027. The low-Earth satellites will rely on RF connectivity and offer a max data transfer speed of 144 Gbps, while the medium-Earth satellites will use optical links to reach the publicized 6 Tbps speed. In comparison, SpaceX's Starlink maxes out at 400 Mbps at the moment, with future upgrades aiming for 1 Gbps.
