Talk about a Halloween treat.

A recently discovered comet will be blazing by the Earth in broad daylight just in time for Halloween, astronomers say.

Comet C/2024 S1, first found at the end of September, will pass around the Earth on Oct. 24, according to planetary astronomer James Wray of the Georgia Institute of Technology, who advises to “look low in the eastern sky just before sunrise.”

Researchers have discovered the Neptunian Ridge, a region packed with planets, located between the Neptunian Desert and Savannah. This finding sheds light on how planets migrate and evolve in different environments.

A new ‘map’ of distant planets has been unveiled by scientists from The University of Warwick, which finds a ridge of planets in deep space, separating a desert of planets from a more populated savannah.

Researchers from Warwick and other universities examined Neptunian exoplanets – these planets share similar characteristics to our own Neptune, but orbit outside of our solar system.

“Through our simulated impacts, we found that the pure water froze too quickly in a vacuum to effect meaningful change, but salt and water mixtures, or brines, stayed liquid and flowing for a minimum of one hour,” said Dr. Michael J. Poston.

How does extra salty water, also known as briny water, form and evolve on worlds without atmospheres, such as asteroids and moons? This is what a recent study published in The Planetary Science Journal hopes to address as a team of researchers investigated how briny water could still flow for a period of time on the asteroid Vesta after large impacts resulted in the melting of subsurface ice. This study holds the potential to help researchers better understand the geological and chemical processes on planetary bodies without atmospheres and what this could mean for finding life as we know it.

“We wanted to investigate our previously proposed idea that ice underneath the surface of an airless world could be excavated and melted by an impact and then flow along the walls of the impact crater to form distinct surface features,” said Dr. Jennifer Scully, who is a planetary geologist at NASA’s Jet Propulsion Laboratory (JPL) and a co-author on the study.

Scientists FINALLY FOUND a new way to travel faster than light!

Continue reading “Scientists FINALLY FOUND a New Way To Travel Faster Than Light!” »

The Cosmicflows team has been studying the movements of 56,000 galaxies, revealing a potential shift in the scale of our galactic basin of attraction. A team of international researchers guided by astronomers at University of Hawai’i Institute for Astronomy is challenging our understanding of the universe with groundbreaking findings that suggest our cosmic neighborhood may be far larger than previously thought.

A decade ago, the team concluded that our galaxy, the Milky Way, resides within a massive basin of attraction called Laniākea, stretching 500 million light-years across.

However, new data suggests that this understanding may only scratch the surface.

Astronomers from the European University Cyprus and the University of Hawaii have investigated a recently discovered obscured hyperluminous quasar known as COS-87259. Results of the study, published October 14 in the Monthly Notices of the Royal Astronomical Society, shed more light on the properties of this quasar.

A plasma jet from galaxy M87 appears to move five times faster than light.

In the world of astronomy, a peculiar and seemingly impossible phenomenon is unfolding in galaxy M87. A beam of plasma, or energy, is shooting out from the galaxy’s core and appears to travel at five times the speed of light, as observed by the Hubble Space Telescope. Though this illusion has been known since 1995, it continues to challenge our understanding of the universe’s laws, particularly the cosmic speed limit that states nothing can move faster than light.

Evidence is found for a distant galaxy growing inside-out within the first 700 million years of the Universe. The galaxy has a dense central core comparable in mass density to local massive ellipticals, and an extended star-forming disc.
