The “Seven Sisters” of the Pleiades are part of a much larger complex that can help reveal our galaxy’s deep history ...

Warm summer nights in August offer a front-row seat to some of the most mesmerizing star clusters in the sky. According toEarthSky.org, this month brings prime viewing opportunities for three of the ...

Astronomers have discovered that the Seven Sisters of the Pleiades star cluster have more stellar siblings than we thought — a lot more. Using NASA's exoplanet hunting spacecraft TESS (Transiting ...

Globular clusters are often described as ancient, tightly bound fossils of the early Milky Way. It has been believed that ...

This is a tale of rediscovery. I have been an astronomer for more than half a century. My current observing concentrates on showcase nebulae and galaxies or the pursuit of fine lunar detail. But ...

Welcome to the Tuesday Telescope. There is a little too much darkness in this world and not enough light—a little too much pseudoscience and not enough science. We'll let other publications offer you ...

A computational model of the early-to-present-day Universe predicts that some of the first stars formed in structures that challenge conventional classification. Read the paper: The emergence of ...

Using the Hubble Space Telescope, astronomers have made the first direct observation of star clusters colliding and merging at the hearts of dwarf galaxies. The discovery could help scientists settle ...

Fig. 1: An image of the star cluster Westerlund 1, captured with the Near-InfraRed Camera on NASA’s James Webb’s Space Telescope. The cluster is largely hidden at visible wavelengths by dust clouds, ...

How do rogue planetary-mass objects -- celestial bodies with masses between stars and planets -- form? An international team of astronomers has used advanced simulations to show that these enigmatic ...

"We were surprised by the streams of light that were visible near the center of the galaxies, as nothing similar has been observed in the past." When you purchase through links on our site, we may ...
