15 Spectacular Events That Occured In Outer Space

Outer space is infinite, and no one really knows where it leads. Many events occur among the stars, and some can be seen by scientists. Join us, as we look at 15 spectacular events that occurred in outer space.

Missing Stars

Across the Milky Way, there are empty spaces where stars once shone brightly. Some left clues in their deaths, while others faded into retirement. Others simply relocated to a new area. However, not all vacancies have such simple explanations. Some appeared and then vanished, sparking speculation about rare types of star death, extreme astrophysics, and, of course, advanced alien technology.

Researchers identified around 100 bright dots that appear to have vanished without a trace by comparing star catalogs dating back to the 1950s with more recent datasets. The search began several years ago as part of an effort to find evidence of alien intelligence. Finding an actual vanishing star - or a star that appears out of nowhere! - would be a priceless discovery that would undoubtedly include new astrophysics beyond what experts currently know.

Nasa Detects Dark Matter Noise

Astronomers discovered that dark matter forms much smaller clumps than previously thought using NASA's Hubble Space Telescope and a new observing technique. This finding confirms one of the key predictions of the widely accepted "cold dark matter" theory. According to this theory, all galaxies form and are embedded within clouds of dark matter. Dark matter is made up of slow-moving, or "cold," particles that combine to form structures ranging in size from hundreds of thousands of times the mass of the Milky Way galaxy to clumps no larger than the weight of a commercial airplane.

Dark matter is an invisible form of matter that makes up most of the universe's mass and serves as the foundation for galaxies. Although astronomers cannot see dark matter, they can indirectly detect its presence by measuring how its gravity affects stars and galaxies. Because they contain so few stars, detecting the smallest dark matter formations by looking for embedded stars can be difficult or impossible.

While dark matter concentrations have been detected in the vicinity of large and medium-sized galaxies, much smaller clumps of dark matter have yet to be discovered. In the absence of observational evidence for such small-scale clumps, some scientists have proposed alternative theories, such as "warm dark matter." This theory proposes that dark matter particles are too fast-moving to merge and form smaller concentrations. The new observations, which show that dark matter is "colder" than it would have to be in the warm dark matter alternative theory, do not support this scenario.
