Small but hyperactive Comet 46P/Wirtanen is approaching Earth and could soon become visible to the naked eye.
New scientific reports are again confirming the electrical nature of one of the most mysterious phenomena in the cosmos, the comet.
They both orbit the sun, but they’re very different.
Ever since space scientists first spotted the odd, cigar-shaped object known as 1I/‘Oumuamua in the sky, they have been debating what it is exactly. Suggestions have included an asteroid, a comet and even alien spaceship. Now a study, published in Nature, suggests it may actually be a comet – but an unusual one.
Scientists from MIT and other institutions, working closely with amateur astronomers, have spotted the dusty tails of six exocomets — comets outside our solar system — orbiting a faint star 800 light years from Earth.
If you have long suspected the mainstream is being less than honest [or simply delusional] when they describe Comets as “dirty snowballs” or [more recently] “icy dirtballs” then you might be interested to discover Close Cometary Encounters are associated with sudden spikes in the level of Thorium 232.
Narrow dense rings of comets are coming together to form planets on the outskirts of at least three distant solar systems, astronomers have found in data from a pair of NASA telescopes.
“Comets travel much faster than asteroids, and some of them are very big,” said Amy Mainzer, co-author based at NASA’s Jet Propulsion Laboratory, Pasadena, California, and principal investigator of the NEOWISE mission. “Studies like this will help us define what kind of hazard long-period comets may pose.”
The finding shows that oxygen can be generated in space without the need for life, and could influence how researchers search for signs of life on exoplanets.
