NASA’s Hubble Space Telescope has captured an image showing what the space agency calls “pocketful of stars” – a section of the universe filled with thousands of multicolored stars. This image shows a “globular” cluster called NGC 1805, located near the galaxy’s satellite Galaxy, the Large Magellanic Cloud.

In a conversation with Drew Barrymore
Actress, producer, director, writer and entrepreneur Drew Barrymore has worn many hats in his 45 years – and he will soon make another donation, hosting a new daytime show “Dhru Barimore Show” which debuted on CBS on Monday. He chats with journalist Lee Cowan about the challenges of starting a new broadcast during the epidemic, the ethics of his lifelong work, and what he has learned about himself from pushing the limits.

Twenty years after its creation, Washington D.C. A new monument has been erected to President Dwight D. Eisenhower, who led the Allies to victory in World War II and then led the United States in the early years of the Cold War. Correspondent Rita Brewer talks to Ike’s granddaughter, Susan Eisenhower, and the monument’s architect, Frank Gehry, about how to best respect the life and consequential legacy of the common and commander-in-chief, whose reputation has only grown over time. .

After news of the coronavirus epidemic broke from almost the first time, prejudice became the lens through which many Americans viewed the dangers of COVID-19 outbreaks – whether hand washing, masks, and social distance were taken seriously. Correspondent Martha Techner spoke with health officials about the public’s response to the coronavirus, and examines how the federal government’s leadership during the health crisis has been disrupted by the fingerprints of politics and the dynamics of the election calendar.
Now the next
In particular, globular clusters contain stars that are born at the same time, NASA said. But NGC 1805 is unusual – scientists believe it has two different populations of stars that are millions of years apart in age.
NASA has compared the closest orbits of stars to bees around a hive. The agency said it is unlikely that the stars in the center will orbit through the planets, as they are 100 to 1000 times closer than the stars closest to our Sun.

The cluster appears in the constellation “Dorado” from the Southern Hemisphere.
Hubble’s position in space gives it the unique ability to capture different wavelengths of light. The Earth’s atmosphere absorbs most of the ultraviolet light, making the cluster difference in star colors impossible to observe from the ground.
The image combines different types of light to highlight significant differences in star colors – blue stars, bright near ultraviolet light, and red stars, bright in red and near-infrared.
To learn more about the evolution of stars, astronomers are interested in observing clusters such as NGC 1805, as well as what factors cause them to die. White dwarf Vs. explosive Supernova.
