Hubble Spots A Community Of Extremely Old Stars That Have Aced Longevity
Globular clusters are communities of stars formed at the same time and place, providing insights into early star formation.
Hubble Space Telescope's clarity of vision from its orbital altitude allows for detailed observations of individual stars in objects like NGC 1841. [ more ]
February 2024: Science History from 50, 100 and 150 Years Ago
NASA plans to launch a 120-inch reflecting telescope in the early 1980s called the Large Space Telescope, which will be able to map the recessional velocities of galaxies and potentially reveal new objects in other galaxies.
The Hubble Space Telescope, originally called the Large Space Telescope, was approved by the National Academy of Sciences in 1969 and was launched in 1990. [ more ]
These Seven Galaxies Snuggled Together Is the Birthplace of the Most Powerful Fast Radio Burst
Astronomers have traced the origin of a powerful fast radio burst (FRB) and discovered seven galaxies clustered together, unlike any other known FRB origin site.
Fast radio bursts (FRBs) are millisecond-long flashes of intense energy that are still a mystery in astronomy. Knowing their origin helps explain why they exist. [ more ]
NASA Experts Concerned Billionaire Space Tourist Will Accidentally Break Hubble Space Telescope While Trying to Fix It
Billionaire Jared Isaacman offers to fund a maintenance mission for the aging Hubble Space Telescope, but NASA is cautious about accepting due to risks and complexities. [ more ]
Happy birthday Hubble, you've got gyro issues again

Hubble Snaps Alarming Pic of Two Galaxies Crashing Into Each Other
NASA's Hubble Space Telescope has captured an image of two massive galaxies colliding with each other.
This collision, known as 'Arp 122,' could eventually form a singular structure of dust, gas, and dark matter in hundreds of millions of years. [ more ]
Hubble Discovers Closest Earth-Sized World to Our Star System
Scientists using the Hubble Space Telescope have measured the size of an exoplanet just 22 light years away, confirming it as the closest known Earth-sized world to our solar system.
The exoplanet, named LTT 1445Ac, has a diameter 1.07 times that of Earth's and a mass of around 1.37 Earths. However, its surface temperature of 500 degrees Fahrenheit makes it uninhabitable for potential life.
To observe exoplanets, astronomers rely on a transit event where the planet passes between a telescope and a star, causing a dip in the star's light. The researchers initially used the TESS satellite to observe LTT 1445Ac, but the Hubble Space Telescope provided conclusive data. [ more ]
NASA's Hubble Space Telescope recently captured a stunning image of Uranus and its moons, showcasing the planet's unique features
The image reveals Uranus with its 13 ring systems, which are believed to be younger than the planet itself and may have formed from destroyed moons. [ more ]
