Comparing Two Black Holes: Sagittarius A* in Our Milky Way and M87*
Size comparison of the two black holes imaged by the Event Horizon Telescope (EHT) Collaboration: M87*, at the heart of the galaxy Messier 87, and Sagittarius A* (Sgr A*), at the center of the Milky Way. The image shows the scale of Sgr A* in comparison with both M87* and other elements of the Solar System such as the orbits of Pluto and Mercury. Also displayed is the Sun’s diameter and the current location of NASA's Voyager 1 space probe, the furthest spacecraft from Earth launched in 1977. M87*, which lies 55 million light-years away, is one of the largest black holes known. While Sgr A*, 27,000 light-years away, has a mass roughly four million times the Sun’s mass, M87* is more than 1000 times more massive. Because of their relative distances from Earth, both black holes appear the same size in the sky.

This artist’s impression depicts a rapidly spinning supermassive black hole surrounded by an accretion disc. This thin disc of rotating material consists of the leftovers of a Sun-like star which was ripped apart by the tidal forces of the black hole. The black hole is labeled, showing the anatomy of this fascinating object.
What does it take to capture an image of the black hole at the center of our galaxy? This video explains how the Event Horizon Telescope (EHT) works, and how astronomers managed to create one massive Earth-sized telescope big enough to “see” at the edge of black holes.

Zoom into Black Hole at the Center of Our Milky Way Galaxy | ESO
Watch as this video sequence zooms into the black hole (Sgr A*) at the centre of our galaxy. Beginning with a broad view of the Milky Way, we dive into the dense clouds of gas and dust at our galactic center. The stars here have been observed with the European Southern Observatory’s Very Large Telescope and ESO’s Very Large Telescope Interferometer for decades, the black hole’s immense gravitational pull distorting the orbits of the stars closest to it. Finally, we arrive at Sgr A*, the first image of which has been captured by the EHT collaboration. The black hole is shown by a dark central region called a shadow, surrounded by a ring of luminous gas and dust.
The various observations used here were taken at different times, by different teams and with different facilities, and put together for the purpose of the zoom effect. The images go from visible wavelengths at the beginning to infrared, with the very final image being taken at radio wavelengths.
First Image of Black Hole at Center of Milky Way Galaxy | Event Horizon Telescope
This is the first image of Sagittarius A*, or Sgr A*, the supermassive black hole at the center of our galaxy. It is the first direct visual evidence of the presence of this black hole. It was captured by the Event Horizon Telescope (EHT), an array which links together eight existing radio observatories across the planet to form a single Earth-sized virtual telescope. The telescope is named after the "event horizon", the boundary of the black hole beyond which no light can escape.
Although we cannot see the event horizon itself, because it cannot emit light, glowing gas orbiting around the black hole reveals a telltale signature: a dark central region, called a "shadow," surrounded by a bright ring-like structure. The new view captures light bent by the powerful gravity of the black hole, which is 4 million times more massive than our sun. The image of the Sgr A* black hole is an average of the different images that the EHT Collaboration has extracted from its 2017 observations.
European Robotic Arm Installed by Russian Cosmonauts | International Space Station
The European robotic arm (ERA) is pictured extending out from the Nauka multipurpose laboratory module during a mobility test several days after Roscosmos cosmonauts Oleg Artemyev and Denis Matveev activated the ERA during a seven-hour and 42-minute spacewalk.
The European Robotic Arm (ERA) successfully made its first moves in orbit during the 250th spacewalk to upgrade the International Space Station (ISS).
Two spacewalkers worked outside the orbiting lab for 7 hours and 42 minutes on April 28, 2022. Russian cosmonauts Oleg Artemyev and Denis Matveev removed thermal blankets and then unlocked the robotic arm.
The duo released the launch locks that held the arm in its folded configuration for the journey to space last year. Inside the International Space Station, crewmate Sergey Korsakov monitored the first commanded movements of the robotic arm.
The robotic arm brings new ways of operating automated machines to the orbital complex. ERA has the ability to perform many tasks automatically or semi-automatically, can be directed either from inside or outside the ISS, and it can be controlled in real time or preprogrammed.
The International Space Station already has two robotic arms—Canadian and Japanese robots play a crucial role in berthing spacecraft and transferring payloads and astronauts.
ERA is the first robot capable of ‘walking’ around the Russian parts of the orbital complex. It can handle components up to 8000kg with 5mm precision, and it will transport astronauts from one working site to another.

SWOT: NASA-CNES Satellite to Survey the World's Water—Mission Overview
NASA and CNES (French Space Agency) are collaborating to make the first global survey of Earth's surface fresh water and study fine-scale ocean currents with a new mission called SWOT, or Surface Water and Ocean Topography. SWOT will collect data on the height of Earth’s salt and fresh water—including oceans, lakes, and rivers—enabling researchers to track the location of water over time, which will help measure the effects of climate change.
SWOT is expected to launch from Vandenberg Space Force Base in central California in November 2022.
SWOT is a collaboration between NASA and the French space agency Centre National d’Etudes Spatial (CNES), with contributions from the Canadian Space Agency (CSA) and United Kingdom Space Agency (UK Space Agency).
Earth from Orbit: First Imagery from New GOES-18 Weather Satellite | NOAA
On May 11, 2022, the National Oceanic and Atmospheric Administration (NOAA) shared the first images of the Western Hemisphere from its new GOES-18 satellite. The satellite’s Advanced Baseline Imager (ABI) instrument recently captured stunning views of Earth.
GOES-18, NOAA’s newest geostationary satellite, launched on March 1, 2022. The ABI views Earth with sixteen different channels, each measuring energy at different wavelengths along the electromagnetic spectrum to obtain information about Earth’s atmosphere, land, and ocean.
GOES-18 orbits 22,236 miles above the equator at the same speed the Earth rotates. This allows the satellite to constantly view the same area of the planet and track weather conditions and hazards as they happen.
The ABI provides high-resolution imagery and atmospheric measurements for short-term forecasts and severe weather warnings. ABI data is also used for detecting and monitoring environmental hazards such as wildfires, dust storms, volcanic eruptions, turbulence, and fog.
Data from multiple ABI channels can be combined to create imagery that approximates what the human eye would see from space—a result known as GeoColor. Combining data from different channels in different ways also allows meteorologists to highlight features of interest.
Recently, GOES-18 observed a number of weather events, environmental phenomena, and striking views of our planet. Storms across east Texas produced large hail, strong wind gusts, and tornadoes. Farther west in New Mexico, strong winds resulted in large areas of blowing dust and expansion of large wildfires. Fog blanketed parts of Chile in South America, and clouds and some thunderstorms formed along sea breezes in the Yucatan and south Florida.
GOES-18 is currently undergoing post-launch testing, validation and calibration of its instruments and systems to prepare it for operations. The ABI cooling system is performing well, with no signs of the issue that affects its sister satellite, GOES-17. The ABI was redesigned for GOES-18 to reduce the likelihood of future cooling system anomalies. The new design uses a simpler hardware configuration that eliminates the filters that are susceptible to debris.
GOES-18 will assist GOES-17 with GOES West operations in late summer 2022 and again in early fall. NOAA plans for GOES-18 to replace GOES-17 as GOES West in early 2023. Imagery from GOES-18 during the post-launch testing phase should be considered preliminary and non-operational.

European Space Agency Astronaut Matthias Maurer Returns to Germany
European Space Agency astronaut Matthias Maurer is back in Cologne, Germany, after 177 days in space and 175 days aboard the International Space Station for his first mission ‘Cosmic Kiss’.
The Crew Dragon spacecraft carrying Matthias and his Crew-3 crewmates, NASA astronauts Raja Chari, Thomas Marshburn and Kayla Barron, splashed down in the Gulf of Mexico off the coast of Tampa, Florida, USA on Friday, May 6, 2022. The journey from the International Space Station to splashdown took just over 23 hours.
After its water landing, the SpaceX Crew Dragon spacecraft was hoisted aboard a recovery boat where the hatch was opened, and the astronauts were welcomed home.
Matthias underwent initial medical checks aboard the boat before being flown by helicopter to shore and boarding a plane to Cologne. He will spend the next weeks participating in debriefings, providing samples for scientific evaluation and readapting to Earth’s gravity at ESA’s European Astronaut Centre (EAC) and the German Aerospace Centre’s (DLR) ‘Envihab’ facility.
