What if we fill a crater on the moon with water? Can we create a lake? Would the water stay in this artificial lake?Continue reading Can we create a lake on the Moon?
Today, climate change is a very real and looming threat. However, when the subject of climate change and possible solutions is discussed, the phrase “we need bigger changes” is often bandied about. Individuals tend to shift the responsibility of fixing human-caused damage to the environment to larger systems – but with little concrete action being taken by larger entities, potential solutions to mitigate climate change remain largely unaddressed and unimplemented.Continue reading How Individual Environmental Action Can Impact Systemic Change
Raise your hand you’re one of those people whose travel bucket list just keeps getting bigger and bigger with each passing day. In fact, chances are you may also be caught staring at the pictures of exotic destinations in between work. You may daydream about hiking through the valleys or soaking in the sun at a beach.
As fascinating as your travel bucket list is, you can’t really ignore the fact that fulfilling your wanderlust comes at a price. Does that mean your travel bucket list will never be checked off? Well, you can still travel your heart’s content without going broke. For that, you need to learn the art of budgeting.
But before you get too excited, let me break it you that budgeting can be the hardest process to get through. You wouldn’t want to think about the hole you’ll be digging into your pockets when you’re out to have fun. But fret not, because I will guide you how to check off all the destinations on your travel bucket list without coughing up an exorbitant amount of money.Continue reading 5 Rules To Remember Before Travelling The World On A Limited Budget
After ʻOumuamua, now we are likely to have another interstellar visitor beyond our solar system: comet C/2019 Q4 (Borisov). So the interstellar objects entering the solar system may not be rare at all.Continue reading Comet C/2019 Q4 (Borisov) – our new interstellar “visitor”
On June 20, 2019, Hubble Space Telescope snapped this beautiful portrait of Saturn and its rings at the ringed planet’s closest approach to Earth. The image was published on September 12, 2019.Continue reading Hubble’s last portrait of Saturn and its rings
With more than 4,000 exoplanets – planets orbiting stars other than our sun – discovered so far, it may seem like we are on the cusp of finding out whether we are alone in the universe. Sadly though, we don’t know much about these planets – in most cases just their mass and their radius.
Understanding whether a planet could host life requires a lot more information. At the moment, one extremely important piece of information that is missing is the presence, composition, and structure of their atmospheres. Signs of atmospheric water, oxygen and methane would all be signs that a planet may support life.
Now we have for the first time managed to detect water vapour in the atmosphere of an exoplanet that is potentially habitable. Our results have been published in Nature Astronomy.Continue reading How we detected water on a potentially habitable exoplanet for the first time
Hurricanes are very powerful tropical storms (also known as a tropical cyclone). When a tropical storm’s maximum sustained winds reach 74 mph (119 km/h), it is called a hurricane.
Hurricane is actually the name of a tropical cyclone that occurs in the Atlantic Ocean and the northeastern Pacific Ocean. In the northwestern Pacific Ocean; in the south Pacific or the Indian Ocean, for example, hurricanes usually known as typhoons.
Hurricanes get classified by their sustained wind speed. The Saffir–Simpson hurricane wind scale (SSHWS) is a 1 to 5 rating based on a hurricane’s sustained wind speed. This scale estimates potential property damage.
Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage. Category 1 and 2 storms are still dangerous, however, and require preventative measures.
Here are 20 amazing hurricane facts.Continue reading 20 Amazing Hurricane Facts
Imagine a rainforest at dawn – the tall canopy laden with dripping ferns and orchids, tree trunks covered in spongy mosses and lichens, and the morning mist only slowly burning away as the sun rises. While there is fuel everywhere, it seems unimaginable that such humid ecosystems could ever catch fire.
And without human intervention, they don’t. The charcoal record points towards infrequent fires in the Amazon even during periods of pre-Columbian human settlement, and the 8,000 or more Amazonian tree species have none of the evolutionary adaptations to fire found in their savanna or boreal cousins.
But, with thousands of fires currently burning across the Amazon, it’s worth looking at how these wildfires behave. In this context, a “wildfire” is one which has gone out of control, even if started by humans. What do they mean for a forest that hasn’t evolved with fire? And what is needed to prevent further damage?Continue reading Amazon fires explained: what are they, why are they so damaging, and how can we stop them?
In any post-apocalyptic survival scenario, it pays to be prepared. Climate change may be a zombie-level existential threat, and the best time to act is right now. Prepare yourself for the worst-case scenario with these climate change preparedness strategies.Continue reading Climate Change Is the New Zombie Apocalypse: Who Will Get Hit the Hardest and How to Prepare
Many people believe that chemicals, particularly the man-made ones, are highly dangerous. After all, more than 80,000 chemicals have been synthesised for commercial use in the United States, and many have been released into the environment without proper safety testing. Should we be afraid of the synthetic chemicals that permeate our world?Continue reading Why synthetic chemicals seem more toxic than natural ones
