Astronomers want to unlock the secrets of the “Cosmic Dawn” by sending a miniature spacecraft to listen out for an “ancient whisper” on the far side of the moon.This post was originally published on this […]

Recreating artificial solar eclipses in space could help astronomers decipher the inner workings of our sun much quicker than if they had to wait for the celestial show on Earth.This post was originally published on […]

Sunspots are the most striking phenomenon of the solar magnetic field. After the invention of the telescope early in the 17th century, the Italian astronomer Galileo Galilei was the first to routinely observe sunspots. In […]

When NASA’s DART spacecraft slammed into the asteroid moon Dimorphos in September 2022, it didn’t just change the asteroid’s orbit as intended—it unleashed a massive barrage of boulders that carried more than three times the […]

Radar systems used by civilian airports and military operations are inadvertently revealing our existence to potential advanced alien civilizations, new research shows.This post was originally published on this site

Cosmic dust does far more than float through space. It’s the raw material from which stars, planets and possibly even life emerge. Yet astronomers have long puzzled over where this vast amount of dust comes […]

Using NuSTAR and XMM-Newton satellites, astronomers from New York University (NYU) Abu Dhabi have observed a pulsar known as PSR J1930+1852 and its pulsar wind nebula (PWN). Results of the observational campaign, published in The […]

Earth and our entire Milky Way galaxy may sit inside a mysterious giant hole which makes the cosmos expand faster here than in neighboring regions of the universe, astronomers say.This post was originally published on […]

Researchers have found clouds of cold gas embedded deep within larger, superheated gas clouds—or Fermi bubbles—at the Milky Way’s center. The finding challenges current models of Fermi bubble formation and reveals that the bubbles are […]
