High chance of interplanetary Panspermia in the recently discovered TRAPPIST-1 stellar system, claimed to be a good possibility by scientists (in multiple studies).

"After NASA announced in February the discovery of a solar system with seven planets—three of which were deemed potentially habitable—UChicago postdoctoral scholar Sebastiaan Krijt began wondering: If a life form existed on one of these planets, could space debris carry it to another?

In research recently published in Astrophysical Journal Letters, Krijt and fellow UChicago scientists conclude that life forms, such as bacteria or single-cell organisms, could travel through the newly discovered TRAPPIST-1—an unusual solar system that presents an exciting new place in the Milky Way to search for extraterrestrial life."

The magnetic field lines between a pair of active regions formed a beautiful set of swaying arches, seen in this footage captured by NASA’s Solar Dynamics Observatory on April 24-26, 2017. The arches are traced out by charged particles spinning along the magnetic field lines. These arches, which form a connection between regions of opposite magnetic polarity, are visible in exquisite detail in this wavelength of extreme ultraviolet light. Extreme ultraviolet light is typically invisible to our eyes, but is colorized here in gold. Read more: https://go.nasa.gov/2pGgYZt

Biosignatures of Exoplanets

Deciding if a gas is a sign of life requires atmospheric chemists to know how big is the rate of production as well as destruction from both biotic and abiotic processes. Astronomers and geochemists need to provide the stellar-planetary context, and microbial ecologists estimates of plausible biological flux rates. For example, oxygen makes up 20% of Earth’s atmosphere – such a large amount cannot occur from hydrogen escape given our planetary setup, so the source must be a life process. N2O from lightning is miniscule on our planet, so any significant amount of N2O must also be from life.

The presence of one gas alone may not be conclusive, but a suite of different gases together can corroborate if one or more is biogenic. Or a biogenic gas might be present, but in so low abundance that it is hard to detect, while its photochemical byproducts couldser... more »

The presence of one gas alone may not be conclusive, but a suite of different gases together can corroborate if one or more is biogenic. Or a biogenic gas might be present, but in so low abundance that it is hard to detect, while its photochemical byproducts could serve as indicators it is there. The simultaneous presence of O2 and CH4 would excite scientists: CH4 should get destroyed quickly by hydroxyl (OH) radicals from H2O vapor, so if it is there with O2, both must be produced by life. Meanwhile, on planets where there is very low UV flux (which generates the OH from H2O), biogenic gases like methyl chloride (CH3Cl) that also normally are destroyed by OH might build up to higher concentrations and be easier to detect.

Star from the Lizard Constellation Photobombs Hubble Observation

In space, being outshone is an occupational hazard. This NASA/ESA Hubble Space Telescope image captures a galaxy named NGC 7250. Despite being remarkable in its own right — it has bright bursts of star formation and recorded supernova explosions— it blends into the background somewhat thanks to the gloriously bright star hogging the limelight next to it.

The bright object seen in this Hubble image is a single and little-studied star named TYC 3203-450-1, located in the constellation of Lacerta (The Lizard). The star is much closer than the much more distant galaxy.

Only this way can a normal star outshine an entire galaxy, consisting of billions of stars. Astronomers studying distant objects call these stars “foreground stars” and they are often not very happy about them, as their bright light iscontami... more »

Only this way can a normal star outshine an entire galaxy, consisting of billions of stars. Astronomers studying distant objects call these stars “foreground stars” and they are often not very happy about them, as their bright light is contaminating the faint light from the more distant and interesting objects they actually want to study.

In this case, TYC 3203-450-1 is million times closer than NGC 7250, which lies more than 45 million light-years away from us. If the star were the same distance from us as NGC 7250, it would hardly be visible in this image.

"You can witness the evolution and destruction of humanity; the end of the Earth and Sun; the dissociation of our galaxy; the heat death of the Universe itself. So long as you have enough power in your space ship, you can travel as far into the future as you like."

Have you ever wondered about time travel? Perhaps you have your destination in the far future, and want to see how it all turns out? Maybe you want to return to the past, and alter the future or present by your actions there? Or maybe you want to freeze time altogether? If you want to know whether it's possible, the physics of relativity holds the answer. Special relativity allows us to control our motion through time by manipulating our motion through space.

The more we move through space, the less we move through time, allowing us to travel as far as we want into the future, limited only by our energy available for space travel. But going to the past requires some specific solutions to general relativity, which may (or may not) describe our physical Universe.

Building a Time Machine

"After some serious number crunching, a UBC researcher has come up with a mathematical model for a viable time machine."

Ben Tippett, a mathematics and physics instructor at UBC's Okanagan campus, recently published a study about the feasibility of time travel. Tippett, whose field of expertise is Einstein's theory of general relativity, studies black holes and science fiction when he's not teaching. Using math and physics, he has created a formula that describes a method for time travel.

"People think of time travel as something as fiction," says Tippett. "And we tend to think it's not possible because we don't actually do it. But, mathematically, it is possible."

The making of "Martian Bricks"

"Explorers planning to settle on Mars might be able to turn the planet's red soil into bricks without needing to use an oven or additional ingredients. Instead, they would just need to apply pressure to compact the soil—the equivalent of a blow from a hammer.

These are the findings of a study published in Scientific Reports on April 27, 2017. The study was authored by a team of engineers at the University of California San Diego and funded by NASA. The research is all the more important since Congress passed a bill, signed by President Donald Trump in March 2017, directing NASA to send a manned mission on Mars in 2033."

Saturn Close Up
Diving through the gap between Saturn and it's Rings, Cassini came within ~ 1,900 miles (3,000 km) of Saturn's cloud tops, and within ~ 200 miles (300 km) of the innermost visible edge of the Rings.
The spacecraft survived this daring plunge, returning the closest ever images of inside Saturn's North Polar Hexagon.

Very distant "Iceball" planet discovered via Microlensing

The planet is located a staggering 13,000 light years away!

"Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be habitable for life as we know it, however, because its star is so faint. But the discovery adds to scientists' understanding of the types of planetary systems that exist beyond our own.

"This 'iceball' planet is the lowest-mass planet ever found through microlensing," said Yossi Shvartzvald, a NASA postdoctoral fellow based at NASA's Jet Propulsion Laboratory, Pasadena, California, and lead author of a study published in the Astrophysical Journal Letters."

"The slowest spinning X-ray pulsar in a globular star cluster has been discovered in the Andromeda galaxy. This object is a small and very dense neutron star pulling gas from a companion star. Infalling gasforms a bright hot spot on the neutron star surface, which creates a light-house effect, because the neutron star revolves every 1.2 seconds"

"Lomonosov Moscow State University scientists published the results of a study of unique ultra-slow pulsar XB091D. This neutron star is believed to have captured a companion only a million years ago, and since then, has been slowly restoring its rapid rotation. The young pulsar is located in one of the oldest globular star clusters in the Andromeda galaxy, where the cluster may once have been a dwarf galaxy."

If there really is no supervoid that can explain the Cold Spot, simulations of the standard model of the universe give odds of 1 in 50 that the Cold Spot arose by chance.

Shanks added: "This means we can't entirely rule out that the Spot is caused by an unlikely fluctuation explained by the standard model. But if that isn't the answer, then there are more exotic explanations.

'Perhaps the most exciting of these is that the Cold Spot was caused by a collision between our universe and another bubble universe. If further, more detailed, analysis of CMB data proves this to be the case then the Cold Spot might be taken as the first evidence for the multiverse - and billions of other universes may exist like our own."

For the moment, all that can be said is that the lack of a supervoid to explain the Cold Spot has tilted the balance towards these more unusual explanations, ideas that will need to be further tested by more detailed observations of the CMB."

Movie research results: Multitasking overloads the brain

The brain works most efficiently when it can focus on a single task for a longer period of time. Previous research shows that multitasking, which means performing several tasks at the same time, reduces productivity by as much as 40%. Now a group of researchers specializing in brain imaging has found that changing tasks too frequently interferes with brain activity. This may explain why the end result is worse than when a person focuses on one task at a time.

Meteors light up the sky, but they also seed night-shining clouds.

Meteors help create noctilucent clouds: The ice crystals that form thes clouds must grow on a foundation of some kind. AIM’s data showed that this base is actually smoke from meteors — tiny microparticles produced when meteors burn up in Earth’s atmosphere.

Launched April 25, 2007, NASA’s Aeronomy of Ice in the Mesosphere mission provides a wealth of new science on Earth’s upper atmosphere. Designed to study noctilucent, or night-shining, clouds, AIM’s data helps scientists understand many upper-atmosphere phenomena, from radio echoes to giant, planet-wide atmospheric waves.

But he says that 10 years of data from AIM has far exceeded the initial expectations. “We’ve made great strides in answering this question and learned far more about the atmosphere than we ever imagined when the mission was conceived.”

"Around 2010, the deep waters of Utah's Great Salt Lake contained high levels of toxic methylmercury. Mercury measurements in waterfowl surrounding the lake led to a rare human consumption advisory for ducks.

But by 2015, 90 percent of the deep mercury was gone.

The disappearance of the mercury was not due to aggressive environmental policies or a wide-ranging cleanup effort. Instead, it's part of a story involving a large-scale unplanned chemistry experiment, a sometimes-stinky lake, and ducks – in which the mercury did not disappear. The story is told in a paper published in Environmental Science & Technology."
