How far we have explored space and how far can we go?

141 AU which is equal to 141 times of the distance between Earth and Sun, Voyager 1 is able to travel the most in history. Even after travelling at the speed of 17 km/sec in space, which may sound a lot, it will take 1,700,000,000 years for Voyager 1 to cross the Milky Way Galaxy. Proxima Centauri, the second closest star from Earth after Sun is 4.2465 light year away and it would took 40,000 years for Voyager 1 to reach it.

Advanced Civilizations Could be Using Dyson Spheres to Collect Unimaginable Energy From Black Holes

Black holes are more than just massive objects that swallow everything around them – they’re also one of the universe’s biggest and most stable energy sources. That would make them invaluable to the type of civilization that needs huge amounts of power, such as a Type II Kardashev civilization. But to harness all of that power, the civilization would have to encircle the entire black hole with something that could capture the power it is emitting.

Street lighting has detrimental impacts on local insect populations

Reported declines in insect populations have sparked global concern, with artificial light at night (ALAN) identified as a potential contributing factor. Despite strong evidence that lighting disrupts a range of insect behaviors, the empirical evidence that ALAN diminishes wild insect abundance is limited. Using a matched-pairs design, we found that street lighting strongly reduced moth caterpillar abundance compared with unlit sites (47% reduction in hedgerows and 33% reduction in grass margins) and affected caterpillar development. A separate experiment in habitats with no history of lighting revealed that ALAN disrupted the feeding...

Baby boomers are more sensitive than millennials, according to the largest-ever study on narcissism

    A new study, the largest-ever conducted narcissism, looked specifically at hypersensitivity, a trait that helps determine how narcissistic people are.  Its findings suggests that, contrary to popular belief, millennials aren’t more sensitive than the baby boomer generation. In fact, it’s the other way around.

Government to ban single-use plastic cutlery

The government has announced plans to ban single-use plastic cutlery, plates and polystyrene cups in England as part of what it calls a "war on plastic". Ministers said the move would help to reduce litter and cut the amount of plastic waste in oceans. A consultation on the policy will launch in the autumn - although the government has not ruled out including other items in the ban.

Early-life sleep disruptions linked to irregular development of the prefrontal cortex

The period of neurodevelopment extending from birth to roughly two years of age is one of frenetic, constant change. Neurons and synapses form, are organized, and are pruned. It is well known that sleep plays a fundamental role in these processes, and disruptions to sleep at this stage can be devastating to neurodevelopment and may be the cause of disorders like autism spectrum disorder (ASD).

Astronomers Locate the Source of High-Energy Cosmic Rays

Roughly a century ago, scientists began to realize that some of the radiation we detect in Earth’s atmosphere is not local in origin. This eventually gave rise to the discovery of cosmic rays, high-energy protons and atomic nuclei that have been stripped of their electrons and accelerated to relativistic speeds (close to the speed of light). However, there are still several mysteries surrounding this strange (and potentially lethal) phenomenon.

Study identifies 579 genetic locations linked to anti-social behavior, alcohol use, opioid addiction and more

An analysis of data from 1.5 million people has identified 579 locations in the genome associated with a predisposition to different behaviors and disorders related to self-regulation, including addiction and child behavioral problems. With these findings, researchers have constructed a genetic risk score — a number reflecting a person’s overall genetic propensity based on how many risk variants they carry — that predicts a range of behavioral, medical and social outcomes, including education levels, obesity, opioid use disorder, suicide, HIV infections, criminal convictions and unemployment.

People low in self-esteem may be less vulnerable to the impact of romantic breakups than previously thought

A new study suggests that previous research may have overestimated the influence of self-esteem on changes in wellbeing following a breakup. The research found that most people felt less satisfied with life in the wake of their romantic relationship ending, but there was only a small difference between those with low and those with high self-esteem.

Can the World's First Space Sweeper Make a Dent in Orbiting Debris?

Decades of space exploration have left a shroud of space junk enveloping Earth. They’re much more than a minor inconvenience—functional satellites, space shuttles that ferry astronauts back and forth and the International Space Station (ISS) all have to dodge and weave through the detritus. Earlier this year, a gaping hole was discovered in a 58-feet-long arm of the ISS, thought to be caused by an object too tiny to track.

Say hi to Hycean worlds, a new class of exoplanet that could host life

More than 4,400 exoplanets have been discovered to date, and in the hunt for whether there may be life out there most of our attention has been focused on Earth-like worlds. But now, astronomers have defined a new class of exoplanet called “Hycean” worlds that could be a promising place to find signs of life.

Female octopuses throw things at males that are harassing them

An analysis of footage of octopuses off the coast of Australia “throwing” shells and silt suggests that they intentionally target – and often hit – other octopuses. In most cases, it is females that do the throwing, often at males that are harassing them. In 2015, Peter Godfrey-Smith at the University of Sydney and his colleagues filmed several common Sydney octopuses (Octopus tetricus) interacting at a site in Jervis Bay dubbed “Octopolis”. It is one of the few places in the otherwise sandy sea bottom where octopuses can make dens, so there are an unusual number of the animals in a small area.
