Pristine Hubble Image Shows an Exciting Exchange Between Two Galaxies

Astronomy, Galactic Astronomy, Science /

The recurring interaction between two galaxies 320 million light-years away has been recorded in a spectacular Hubble picture. They are collectively named Arp 282 in Halton Arp’s Atlas of Peculiar Galaxies. They feature a large barred spiral galaxy called NGC 169, approximately 140,000 light-years across, and a considerably smaller polar-ring galaxy labeled IC 1559, which is about 40,000 light-years across. These two galaxies have come close […]

Astronomers Identify Remains of Long-Lost Galaxy Consumed by the Milky Way

Astronomy, Galactic Astronomy, Science /

The massive appetite of a Galaxy The Milky Way galaxy devoured more galaxies in its early days than astronomers assumed. The Gaia spacecraft discovered the remains of an ancient cosmic collision in our Milky Way, uncovering a formerly unidentified galaxy, now nicknamed “Pontus,” consumed by the Milky Way prior to our galaxy looking the way

Did Civilization Rise Because of a Comet Impact?

Astronomy, Planetary Geology, Science /

Human beings unexpectedly changed around 13,000 years ago. Hunter-gatherer societies began to transform their lifestyle quickly. They began to construct permanent settlements and focused their efforts on farming. The earliest man-made megalithic structures around were also constructed around this period. Was a comet collision the reason behind this fast advancement of human civilization? An international

The Largest Galaxy Ever Seen Has Just Been Discovered

Astronomy, Cosmology, Science /

Astronomers have just discovered an absolute beast of a galaxy Hiding some 3 billion light-years away, Alcyoneus is a giant radio galaxy reaching five megaparsecs into space. That is 16.3 million light-years long and represents the biggest recognized structure of galactic origin. The finding highlights our poor understanding of these colossi and what drives their

Parker Solar Probe Captures Its First Images of Venus’ Surface in Visible Light

Astronomy, Planetary Science, Science /

NASA’s Parker Solar Probe has taken its first visible-light pictures of the surface of Venus from space Surrounded in thick clouds, Venus’ surface is usually hidden from view. However, in two current flybys of the Earth, Parker used its Wide-Field Imager, or WISPR, to image the whole nightside in wavelengths of the visible spectrum– the

NASA Telescope Idea Could Spot Vegetation on Distant Exoplanets

Astronomy, Planetary Science, Science /

NASA states it could detect “surface features” and even “hints of habitability” on distant planets. NASA is financing research for a conceptual telescope called a “solar gravitational lens” (SGL) that can allow us to observe remote exoplanets at a fantastic resolution– a futuristic endeavor that might assist discovery at last if we are alone in

Too Many Disk Galaxies Than Theory Allows

Astronomy, Cosmology, Science /

The Standard Model of Cosmology defines how the universe came into being according to the perspective of most physicists. Researchers at the University of Bonn have actually currently studied the evolution of galaxies within this model, finding considerable inconsistencies with real observations. The University of St. Andrews in Scotland and Charles University in the Czech
