Millions of stars light up largest and most detailed shot of Milky Way’s centre

Wed 24 Jun 2026

The dazzling sight of more than 60m stars at the heart of Earth’s galaxy has been captured by a space telescope designed to reveal the mysterious dark forces that shape the universe.

Astronomers used the European Space Agency’s Euclid telescope to capture the largest, most detailed image ever taken of the visible light pouring from the centre of the Milky Way. The telescope’s camera is rare in being sensitive enough to separate individual stars in the crowded region known as the galactic bulge.

The enormous image marked the start of a new age of discovery of planets outside Earth’s solar system, researchers said. The number of known worlds is expected to rocket beyond the thousands already spotted around faraway stars.

Dr Eamonn Kerins, an astrophysicist at the University of Manchester’s Jodrell Bank Centre for Astrophysics, said of the Euclid telescope: “It was never built with this science in mind, but it has proved to be a superb facility for the work.

“This data fires the starting pistol in a new age of exoplanet discovery, where we go from knowing about 6,000 exoplanets to finding more than 100,000 across the galaxy.”

World's first commercial nuclear-powered payload now in orbit
By David Szondy
July 07, 2026
City Labs has launched the world's first commercial satellite carrying a nuclear-powered payload into orbit. Lofted atop a SpaceX Falcon 9 rocket, the Betavoltaic Orbital High-Reliability (BOHR) CubeSat is designed to demonstrate using tritium as an energy source.

Nuclear power for spaceflight has been around since long before the first Sputnik went into orbit in 1957. In fact, the idea of splitting atoms for propulsion and power was being seriously considered almost as soon as the first atomic explosions were made public. It was even being tested in orbit as early as 1961 with the US Navy's Transit navigational satellites.

The United States and the Soviet Union used nuclear power for a series of military and experimental government satellites – usually for missions that required more power than solar panels could supply, including radar reconnaissance and meteorological satellites. As satellite arrays became larger and more efficient, and electronics more sophisticated, orbital nuclear power systems were largely confined to exploration missions to the outer Solar System by the 1990s.

Which 10 atmospheres are the Solar System’s thickest?
By Ethan Siegel
August 3, 2026

Introduction:
(Big Think)
• The thickest atmospheres in the Solar System, unsurprisingly, belong to the four gas giant worlds, followed by Venus, Titan, and Earth in the fifth through seventh spots.

• Mars comes in at eighth place after that, possessing less than 1% of Earth’s atmospheric pressure at its surface. But once we look for which world comes next, the pressures drop spectacularly.

• Triton’s atmosphere is 9th overall (but 2nd among moons) and Pluto’s is 10th, in terms of raw pressure. The “honorable mention” worlds below (see link)...however, are the most surprising of all.

Radio Telescopes Help Scientists Map Molecules in Space and Uncover Where and How Stars Form
By Olivia Harper Wilkins
August 14, 2026

Introduction:
(The Conversation) You may have heard the phrase “we are made of star-stuff.” This statement by the astronomer Carl Sagan refers to the fact that elements heavier than hydrogen and helium were forged in the centers of the first stars. But how does this star-stuff evolve into the chemistry of rocks, plants and people?

As an astrochemist and radio astronomer, I study the places in the universe where stars are born as interstellar laboratories. I’m interested in how simple ingredients come together to form bigger and bigger molecules, including those that are building blocks of life. One way I do this is by mapping molecules in space and finding patterns between how abundant they are and the conditions around them.

Astronomers have mapped the distribution of molecules in interstellar space for several decades. From these maps, astronomers typically describe molecules’ abundances, temperatures and how fast they’re moving in each region.

Technology and techniques have improved over time, and now scientists are able to map these metrics at even more precise scales. My research team and I recently compared the findings from these newer methods against previous maps to make sure the earlier maps are consistent with our new maps.
Conclusion:
While replication studies like this one may not seem quite as exciting as studies that yield groundbreaking new results, they’re an important part of the scientific process. As technologies such as radio telescopes improve, astrochemists will be able to make new discoveries, double-check existing observations and study these faraway regions in more detail than ever before.

imagine being so morally bankrupt that all it takes for Donald "Epstein" Trump to increase your opinion of him is to make rocket go zoom
