Astronomers Catch Black Hole Spewing Matter After Feeding

Black holes are some of the most awe-inspiring and mysterious celestial objects in the universe. This is primarily because astronomers still don’t understand the underlying mechanisms that drive black holes, including its formation, evolution, and end. As their name implies, black holes can’t be viewed directly since they blend into the background of the vastness of space. Therefore, astronomers are limited to “seeing” black holes when they consume other celestial objects, most notably stars. When this happens, the astronomers see the light from the star being violently consumed by a nearby black hole in a spectacular display. However, astronomers are still puzzled regarding what happens after the consumption. from Universe Today https://ift.tt/ql9OvIR via IFTTT

Quantum Physicist Takes Aim at the Universe's Mysterious Arrow of Time

Scientists and philosophers have argued over the nature of time since … well, since time immemorial. Is time real, or is it a convenient illusion? Why does time seem to flow in just one direction? In a new book called “On Time,” British physicist Jim Al-Khalili lays out what he thinks is the answer to such questions. from Universe Today https://ift.tt/923Rtxy via IFTTT

ESA JUICE probe targets dark Jovian moon Kallichore in 2031

The planet Jupiter hosts more than 100 moons with the majority of attention going to the four Galilean moons, Io, Europa, Ganymede, and Callisto. This is primarily due to their active geology, including Io being the most volcanically active planetary body in the solar system and Europa having a vast subsurface liquid water ocean beneath its icy crust. However, Jupiter’s smaller and lesser-known moons could provide astronomers key insights into the history of the solar system since they’ve remained largely unchanged, unlike the Galilean moons. from Universe Today https://ift.tt/ula0TcX via IFTTT

7-stage journey reveals how falling space rocks survive air

At least once in our lives, we’ve all seen a bright streak of light briefly blaze across the sky and have quickly referred to it as an asteroid, meteor, shooting star, comet, or some other whimsical name we’ve heard others use to describe it. For those calling it a meteor, you would be correct, but we’ll touch upon this later. The time it takes for a space rock, bolide being its scientific name, to travel through Earth's atmosphere and crash into the ground literally takes only a few seconds. But what happens to a space rock during this very brief travel time, and how can scientists use this to learn about a specific space rock’s origin and the potential damage it could cause if it explodes in mid-air? from Universe Today https://ift.tt/769a2Nx via IFTTT

Gardening the Moon's Cosmic Archives

When a meteoroid hits the Moon's surface, it does more than just dig up a little dirt. It actually excavates a little bit of cosmic history that recorded a long-ago supernova explosion. Scientists at the University of Hawaii Institute of Geophysics and Planetology have come up with a way to decode that history and learn something about such energetic events in the Universe. from Universe Today https://ift.tt/GtCqujH via IFTTT

Ancient Dust Grains Hold Magnetic Clues to the Sun's Birth

Those little dust grains that fall to Earth during meteor showers or end up as part of larger meteorites found on Earth may hold surprising clues to the formation of the Sun. That's because they record the state of the magnetic field in the protostellar nebula from which Earth (and ultimately the planets) formed. from Universe Today https://ift.tt/Lc2qCab via IFTTT
