astronomy121 giant exoplanets in habitable zones may have habitable moons

No Comments
Researchers have identified more than 100 giant planets that potentially host moons capable of supporting life. Their work will guide the design of future telescopes that can detect these potential moons and look for tell-tale signs of life, called biosignatures, …

astronomyCeres has 5-8 times more organic material than previously believed

No Comments
A new analysis of data from NASA’s Dawn mission suggests that organic matter may exist in surprisingly high concentrations on the dwarf planet’s surface. To get an initial idea of how abundant those compounds might be, the original research team …

astronomyColliding wormholes will have gravitational echoes which could be detectable

No Comments
The gravity waves that were detected might have been from the collision of wormholes. If there are gravitational echoes then the collision was from wormholes and not blackholes. There is a problem with black holes—they present an edge, called an …

The Carnival of Space 563 is at Everyday Spacer. Universe Today- There was Evidence for Europa’s Geysers Hiding in Plain Sight in Old Spacecraft Data From 1997 Jupiter’s moon Europa continues to fascinate and amaze! In 1979, the Voyager missions …

astronomyStronger Europa Water Plume evidence and analysis

No Comments
Newly analyzed Galileo data provides “compelling independent evidence that there seems to be a plume on Europa,” said study lead author Xianzhe Jia, an associate professor in the Department of Climate and Space Sciences and Engineering at the University of …

astronomyPerformance simulation of a next generation space based gravity detector starting in 2034

No Comments
The next-generation gravity observatory, called LISA, is expected to be in space in 2034, and it will be sensitive to gravitational waves of a lower frequency than those detected by the Earth-bound Laser Interferometer Gravitational-Wave Observatory (LIGO). A new Northwestern …

astronomyRobert Zubrin says we can find alien life with planets with free oxygen

No Comments
Robert Zubrin says it takes life to create an atmosphere with free oxygen. If we analyze the spectrum of atmosphere for exoplanets and find free oxygen he argues we will have found alien life. If we find a region of …

astronomy2,000-20,000 rogue Moon to Jupiter planets per main sequence star

No Comments
Previously, planets have been detected only in the Milky Way galaxy. Researchers show that quasar microlensing provides a means to probe extragalactic planets in the lens galaxy, by studying the microlensing properties of emission close to the event horizon of …

astronomyCould a Multiverse be hospitable to life?

No Comments
A Multiverse – where our Universe is only one of many – might not be as inhospitable to life as previously thought, according to new research. Questions about whether other universes might exist as part of a larger Multiverse, and …

astronomyBlackhole consumes a mass or our sun every two days and has a mass of 20 billion suns

No Comments
Astronomers at ANU (Australia National University) have found the fastest-growing black hole known in the Universe, describing it as a monster that devours a mass equivalent to our sun every two days. The astronomers have looked back more than 12 …
