Comet’s Trip Past Earth Offers First in a Trio of Opportunities

Comet’s Trip Past Earth Offers First in a Trio of Opportunities

Comet hunters still have a chance to see comet 45P/Honda-Mrkos-Pajdušáková in the next few days using binoculars or a telescope. It’s the first of a trio of comets that will -- between now and the end of 2018 -- pass close enough to Earth for backyard observers to try to spot and for scientists to study using ground-based instruments.

The magellenic clouds stay connected by a string of stars

The magellenic clouds stay connected by a string of stars

Astronomers have finally observed something that was predicted but never seen: a stream of stars connecting the two Magellanic Clouds. In doing so, they began to unravel the mystery surrounding the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC). And that required the extraordinary power of the European Space Agency’s (ESA) Gaia Observatory to do it.

Brain scanners allow scientists to ‘read minds’ – could they now enable a ‘Big Brother’ future?

Brain scanners allow scientists to ‘read minds’ – could they now enable a ‘Big Brother’ future?

Are you lying? Do you have a racial bias? Is your moral compass intact? To find out what you think or feel, we usually have to take your word for it. But questionnaires and other explicit measures to reveal what’s on your mind are imperfect: you may choose to hide your true beliefs or you may not even be aware of them.

Scientists estimate solar nebula’s lifetime

Scientists estimate solar nebula’s lifetime

About 4.6 billion years ago, an enormous cloud of hydrogen gas and dust collapsed under its own weight, eventually flattening into a disk called the solar nebula. Most of this interstellar material contracted at the disk’s center to form the sun, and part of the solar nebula’s remaining gas and dust condensed to form the planets and the rest of our solar system.

Hubble Witnesses Massive Comet-Like Object Pollute Atmosphere of a White Dwarf

Hubble Witnesses Massive Comet-Like Object Pollute Atmosphere of a White Dwarf

The international team of astronomers observed the white dwarf WD 1425+540, about 170 light-years from Earth in the constellation Boötes (the Herdsman) [1]. While studying the white dwarf’s atmosphere using both the NASA/ESA Hubble Space Telescope and the W. M. Keck Observatory the team found evidence that an object rather like a massive comet was falling onto the star, getting tidally disrupted while doing so.

NASA Team Looks to Ancient Earth First to Study Hazy Exoplanets

NASA Team Looks to Ancient Earth First to Study Hazy Exoplanets

For astronomers trying to understand which distant planets might have habitable conditions, the role of atmospheric haze has been hazy. To help sort it out, a team of researchers has been looking to Earth – specifically Earth during the Archean era, an epic 1-1/2-billion-year period early in our planet’s history.

NASA sent a twin to space to study nature versus nurture – and we’re starting to get results

NASA sent a twin to space to study nature versus nurture – and we’re starting to get results

NASA astronaut Scott Kelly recently spent one year in space, while his identical twin brother Mark (a former NASA astronaut himself) stayed on Earth. The mission was part of an important health experiment, looking at how being in space affects our bodies. While the data are still being studied carefully, NASA recently released some intriguing preliminary findings.

Does an anomaly in the Earth’s magnetic field portend a coming pole reversal?

Does an anomaly in the Earth’s magnetic field portend a coming pole reversal?

The Earth is blanketed by a magnetic field. It’s what makes compasses point north, and protects our atmosphere from continual bombardment from space by charged particles such as protons. Without a magnetic field, our atmosphere would slowly be stripped away by harmful radiation, and life would almost certainly not exist as it does today.

Uber brings in NASA engineer to build flying cars

Uber brings in NASA engineer to build flying cars

Flying cars have become something of a hot ticket item of late. In the past few years, companies like Terrafugia, Aeromobil and Moller International have all grabbed headlines with their particular designs. And soon enough, international transportation giant Uber could be joining the ranks of those looking to turn a popular staple of science fiction into science fact.

NASA Finds Planets of Red Dwarf Stars May Face Oxygen Loss in Habitable Zones

NASA Finds Planets of Red Dwarf Stars May Face Oxygen Loss in Habitable Zones

The search for life beyond Earth starts in habitable zones, the regions around stars where conditions could potentially allow liquid water – which is essential for life as we know it – to pool on a planet’s surface. New NASA research suggests some of these zones might not actually be able to support life due to frequent stellar eruptions – which spew huge amounts of stellar material and radiation out into space – from young red dwarf stars.

Do vegetarians live longer? Probably, but not because they’re vegetarian

Do vegetarians live longer? Probably, but not because they’re vegetarian

In the past few years, you may have noticed more and more people around you turning away from meat. At dinner parties or family barbecues, on your social media feed or in the news, vegetarianism and its more austere cousin, veganism, are becoming increasingly popular.

NASA's Curiosity Rover Sharpens Paradox of Ancient Mars

NASA's Curiosity Rover Sharpens Paradox of Ancient Mars

Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planet’s surface. Yet, the ancient sun was about one-third less warm and climate modelers struggle to produce scenarios that get the surface of Mars warm enough for keeping water unfrozen.

Don’t panic: the northern lights won’t be turning off anytime soon

Don’t panic: the northern lights won’t be turning off anytime soon

The northern lights are nature’s very own magnificent light show. They are the mesmerising end result of electrically charged particles from the sun colliding with the Earth’s upper atmosphere. Though more frequently witnessed from the polar regions, the UK and other places on similar latitudes are lucky enough for the aurora borealis to occasionally grace their night sky.
