Mercury , Venus , Mars , Jupiter , and Saturn : those are the planets stargazers in the Northern Hemisphere will be able to glimpse this week during what The Weather Channel called a planet parade. While you won’t be able to spot them all at the same time, you could snag views of Mercury and Venus after sunset and Mars, Jupiter, and Saturn before dawn — read on to find out how. March is an excellent month for “catching all five bright planets,” according to EarthSky . They define bright planet as one in our solar system that can be viewed without an optical aid “and that’s been watched since time immemorial.” Whoa! Cool. In March 2018, you can see all 5 bright planets. https://t.co/kwFqw9Gzhk Look west after sunset for Mercury and Venus. Mars, Jupiter and Saturn are up before dawn. #Mercury #Venus #Jupiter #Mars #Saturn #visibleplanets pic.twitter.com/oyss7rrvb2 — EarthSky (@earthskyscience) March 2, 2018 Related: Google maps the solar system for armchair space travelers Catch Mars, Jupiter, and Saturn before dawn; according to EarthSky, Jupiter should rise around one hour after midnight, and Mars and Saturn appear closer to dawn. The planets have slightly varying rising times depending on where you are on Earth ; EarthSky recommends a few sky almanacs accessible here . The Weather Channel said people in the Rocky Mountains and areas in the South will have the best opportunity for viewing on Wednesday morning. On Thursday morning, the South and areas in the West will be the best locations. If you’re in the Northeast, you might be out of luck; Winter Storm Quinn could obstruct the view, according to meteorologist Chris Dolce. See all 5 bright planets in March https://t.co/Tol9xs2C3L You can't see them simultaneously. But, especially from the Northern Hemisphere, March 2018 is a great month for catching all 5 bright planets either after sunset, or before dawn. pic.twitter.com/tE7rkvHOYs — EarthSky (@earthskyscience) March 2, 2018 Mercury and Venus will appear close together in the first few weeks of March, and you can catch them in the west after sunset. Venus is around “12 times brighter than Mercury,” so EarthSky recommends searching for Venus if you’re having trouble finding our solar system’s smallest planet. If you’re in the Southern Hemisphere, don’t worry! You’ll get your shot at spotting the five planets in April.

Comments Off on David Adjaye unveils designs for National Cathedral in Ghana

In celebration of Ghana’s 61st year of independence, President Nana Addo Dankwa Akufo-Addo revealed designs for a National Cathedral of Ghana to be built in Accra. The government appointed David Adjaye to design the project, a Ghanian British architect of Adjaye Associates who rose to international prominence for his work on the National Museum of African American History and Culture in Washington, D.C. The multi-faith landmark will be a multifunctional space home to Africa’s first Bible Museum and Documentation Center as well as venue for presidential inaugurations and state funerals. The new National Cathedral will be built on a 15-acre landscaped site next to Osu Cemetery. Envisioned by Adjaye as a “physical embodiment of unity, harmony and spirituality,” the multi-faith building will house a series of grand chapels , baptistery, two-story 5000-seat auditorium, music school, central hall, choir facilities, art gallery, retail, and other multipurpose space. The building’s adornments and furnishings will be designed in collaboration with Ghanaian and African artists. Related: National Museum of African American History and Culture opens in Washington, DC A new ceremonial route and landscape will link the Cathedral to prominent Accra landmarks including Independence Square, the State House, and Africa Unity Circle. “It is an immense honour to be granted the opportunity to contribute something of this scale and import to my home country,” said Adjaye. “I have sought to craft a building that not only understands its landscape but one that will be unique to Accra and the Ghanaian Nation.” + Adjaye Associates Via ArchDaily Images via Adjaye Associates

NASA communicates with spacecraft 13 billion miles from Earth

Comments Off on NASA communicates with spacecraft 13 billion miles from Earth

For the first time in 37 years, NASA has communicated with Voyager 1 – which is 13 billion miles away from Earth. The space agency made contact with the spacecraft to reorient it and activate its back-up thrusters to better send information back to Earth. Launched in 1977, Voyager 1 is the only known spacecraft cruising beyond our solar system. Prior to leaving, Voyager 1 and its sister ship Voyager 2 gathered, then transmitted to Earth, the first detailed data from Jupiter , Saturn and Titan, Saturn’s largest moon. NASA’s most recent communication with the spacecraft has made adjustments to its alignment, which should extend its usable life by two to three years as it continues its flight into new interstellar territory. Voyager 1 still communicates with scientists on Earth through the Deep Space Network, a communications system designed in the 1970s that allowed the most recent adjustments to Voyager 1’s trajectory to occur. Voyager 1 has primarily used its main thrusters, which periodically make adjustments to the spacecraft’s flight path to ensure optimum functionality. However, over the years, the main thrusters have become worn down, requiring the earthbound team to turn to Voyager 1’s back-up thrusters, which had not been used since 1980.  “The Voyager flight team dug up decades-old data and examined the software that was coded in an outdated assembler language, to make sure we could safely test the thrusters,” said Chris Jones, chief engineer at NASA’s Jet Propulsion Laboratory (JPL). Related: SpaceX to launch reused rocket in a historic first for NASA Despite its long hibernation, Voyager 1’s back-up thruster system returned to duty without major incident. “The Voyager team got more excited each time with each milestone in the thruster test,” said Todd Barber, propulsion engineer at JPL. The mood was one of relief, joy and incredulity after witnessing these well-rested thrusters pick up the baton as if no time had passed at all.” The team intends to conduct the same operation with Voyager 2, which is expected to leave the solar system within the next few years.

NASA announces alien life could be thriving on one of Saturn’s moons

Comments Off on NASA announces alien life could be thriving on one of Saturn’s moons

In a live broadcast today, NASA researchers announced the agency has uncovered the existence of key ingredients for life as we know it on Saturn’s icy moon, Enceladus . Scientists already knew that the moon had liquid water on the surface, due to the presence of geysers spewing water near the moon’s south pole. Now, hydrogen has been detected in those jets of water, which suggests the strong possibility that Enceladus’s oceans could support microbial life. It may seem strange that an ice-covered world like Enceladus is being looked at as a potential source of extraterrestrial life, but beneath the planet’s icy shell spans a worldwide ocean over a rocky core. The ice is thought to act as a protective outer layer for the sea, the same way that our atmosphere protects Earth and makes life possible on our own planet. In fact, NASA is closely observing many of these “ ocean worlds ” for signs of life. While Enceladus’s geysers have been known to scientists since 2005, this is the first time the Cassini probe has been able to detect any traces of possible life within them. It’s believed that the plumes originate in a hydrothermal system within the moon’s core, estimated to be 2 1/2 times more powerful than the one that drives Yellowstone’s geysers and hot springs. Despite the icy outer shell, the gravitational pull of Saturn provides heat for the water in the moon’s interior, another encouraging sign for the development of life. Related: Trump plans to strip NASA’s earth science division, promote mission to Mars This new information about the moon comes from October 2015, when the Cassini craft flew into the plumes themselves, a mere 30 miles above the moon’s surface. The probe was able to capture particles from the plume inside a piece of equipment called an Ion Neutral Mass Spectrometer, which can analyze the makeup of material encountered on its journey through space. The probe detected a number of interesting organic molecules, including molecular hydrogen, carbon dioxide, and methane. The level of hydrogen , in particular, was surprising to researchers . This volatile gas isn’t easily captured on small, icy worlds like Enceladus, so there must be some chemical process beneath the surface producing the molecules. It may be that hot water from the ocean is flowing into iron-rich cracks in the sea floor, causing a chemical reaction that is constantly replenishing the ocean’s supply of molecular hydrogen. This is the same process that happens in Earth’s own hydrothermal vents , which helps fuel the strange and diverse ecosystems of the deep oceans. Because we’re familiar with exactly how this process supports Earth life, there’s a strong possibility that life could thrive on Enceladus in the same way. Unfortunately, we don’t currently have the instruments necessary to detect life directly on these watery worlds – only to look for the chemical indications of an environment that could potentially support it. Related: NASA discovers 7 Earth-sized planets outside our solar system NASA also today announced that they had found evidence of similar water plumes on Jupiter’s moon Europa , though less is known about their makeup. Unlike the Saturn Cassini mission, scientists don’t currently have an up-close view of Europa. Instead, they had to rely on data from the Hubble Space Telescope , which has been monitoring the moon to try to learn more about the makeup of its oceans. We may not know for certain until the 2020s, when NASA’s Europa Clipper mission is scheduled to launch. Via NASA Images via NASA/JPL

Comments Off on NASA is looking for alien life on Europa

“ Is there life on Mars? ” Perhaps the question is a bit dated. While the past existence of Martian life seems increasingly likely , scientists look towards Jupiter’s moon Europa as one of the solar system’s top candidates for contemporary extraterrestrial life. Located 390,400,000 miles from Earth, Europa is covered by an icy crust that conceals a vast ocean that may be hospitable to life. “After five billion years with conditions like that, it could be a very habitable place,” says Jim Green, director of NASA’s planetary science division. “We believe the environment is just perfect for the potential development of life.” NASA has released details of its previously announced mission to Europa , which outline exactly how scientists will gather data to learn more about Europa’s life-sustaining qualities.   Read the rest of NASA is looking for alien life on Europa Permalink | Add to del.icio.us | digg Post tags: alien life , europa , Europa ocean , extraterrestrial life , jupiter , Jupiter’s moon , liquid water , nasa , NASA equipment , solar system , space exploration

Comments Off on NASA’s Juno Spaceship to Jupiter Will Make the Most Distant Use of Solar Power Ever

NASA is prepared to launch a mission to Jupiter this week that will probe deep into the planet’s clouds to reveal what it is made of. The Juno spacecraft will also make history by being the most distant space probe to use solar panels as its primary source of electricity. The decision charts a new course for deep space missions that traditionally used a radioactive battery, and it stands to prove the viability of solar technology even when the sun is 5 times further away than it is from our home planet.

Comments Off on The Clos-O-Mat Toilet Saves Water and Energy

Let’s think about going to the toilet for a second (stop sniggering at the back). As crucial as they are to our daily lives, most toilets are not the greenest household appliances. Each flush uses about 3-5 gallons of water , while the creation of a single roll of toilet paper uses 37 gallons of water, 13 kWh of electricity and 1.5lbs of wood. In order to make our time on the throne more environmentally friend, UK company Total Hygiene have developed the Clos-O-Mat – a combined toilet/bidet and drier. According to Total Hygiene, the Clos-O-Mat only uses a 1/10th of the water and energy required to produce just a single roll of toilet paper, not to mention 0% of the wood. Read on to learn how it works!
