Has humanity really gone to tatters? Just what is wrong with this world and some of the people living here. Why can’t we appreciate other people or other animals. Why is this simple thing so hard to get through? We are in 21st century, fighting amongst ourselves, blaming each other whether for the pandemic, for the poor decision making, for inequality and more.
Why can’t we all come together and stand united? How does the color of skin matter? You learn and understand people as you talk to them, get to know them. Can you really tell what skin color or what religion the other person is while talking on the phone? No. You can’t. You talk to everyone equally, be sweet with people who talk nicely, be rude to people who are abusive.
So why can’t we do this face to face? Where does the religion or color card come in. Are you stupid?
And then the worst people are there who harm creatures that don’t even have the ability to speak. Just read the article below… I mean how can anyone do that? 😔 Incidents such as these are heart wrenching.
At the end of the day, it’s the responsibility of each and every one of us to educate others. Help others. And then who don’t listen, they need to be dealt with.
Eventually, there will be a nuclear war, or an asteroid collision on Earth or a rogue AI, or environmental destruction that might cause problems to live on Earth. Well those are some of the few reasons Elon Musk is so interested in the Living in Mars concept or inter-planetary capabilities.
According to Elon Musk’s timeline, if all goes smoothly, the first manned mission to Mars can be held as early as 2023. And the idea of transferring 1 million people to Mars, thus starting a civilization, can happen in 40 – 100 years.
The lift-off thrust from the Earth will be 13,000 tons, quite tectonic, for a rocket to speed by and reach Mars in as many as 30 days. However, currently the cost per person to travel to Mars comes out to an approximate $10 billion, which should be reduced by 5 million percent according to Musk. Reducing the price will allow more people to travel to the red planet.
The spaceships design has been summed up as not complicated, however the critics point out that it runs contrary to the reputation of this field of science.
A Mars vision, and sending a million people to the planet within 40 – 100 years. People won’t be wrong of calling Musk overly-ambitious, however he does hold on to what he says, like the re-usability of rockets, that is saving millions of dollars for everyone. So keep your fingers crossed.
NASA and ISRO will be teaming up to build the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, an Earth imaging satellite. The project cost will be close to $1.5 billion.
NISAR is the first big collaboration between NASA and ISRO, certainly on RADAR but just in general as well. This is two frequency RADAR, it is an L-band 24 centimeter RADAR and S-band 13 centimeter. S-band is being built by ISRO and L-band by NASA.
The satellite is scheduled to be launched in 2021 using the Geo-synchronous satellite launch vehicle (GSLV).
The satellite will be used to take snapshots of the Earth, images of the motion of tectonic plates, of ice sheets, of agricultural land changes and forests. Also include natural disasters like earthquakes, volcano eruptions and sea level rise.
NASA has spotted a man-made barrier around the Earth that prevents high-energy space radiation from reaching the planet. VLF (Very Low Frequency) radio communications interact with particles in space, affecting how and where they move. These interactions can create a barrier around the Earth against natural high energy particle radiation in space.
The bubble barrier can be seen by a spacecraft above the Earth’s surface, such as NASA’s Van Allen Probes. It is speculated that without the man-made VLF transmissions, the boundary of the barrier would have probably been closer to the Earth.
This VLF transmissions barrier can serve as a way to remove excess radiation from the near-Earth environment.
One of the world’s most remote places, Henderson Island, has a population of 0, but it’s beaches has a high density of plastic pollution, more than anywhere in the world.
Henderson Island, located roughly halfway between Chile and New Zealand, is around 3107 miles from the nearest population center, yet it is polluted by 37.7 million pieces of plastic. The density of plastics is believed to be 671 items per square meter! And more than 3,570 pieces of trash gets deposited on the beach daily, which only includes pieces bigger than 10 millimeters.
Since the island is located close to the center of the South Pacific Gyre ocean current, it is a key location for debris to get accumulated. All this debris is mainly released in the oceans by South American countries or fishing boats.
We need to note that plastic debris is a hazard for many species who are entangled in it, or ingest it. Yet more than 300 million tonnes of plastic manufactured annually goes un-recycled, leaving a long-term impact on oceans.
An asteroid, named 2014-JO25, will pass through Earth at a distance of 1.8 million kilometers, (five times the distance from the moon). The asteroid stretches 650 meters across and is believed to pass Earth today.
The asteroid will pass closest to Earth after having looped around the Sun, and will continue on past Jupiter before heading back toward the center of our Solar System.
The last time an asteroid of this size or bigger passed was in 2004, named Toutatis, which was five kilometers across, and passed within four lunar distances.
2014-JO25 is beileved to have passe Earth previously around 400 years ago, and will pass Earth again in 2600.
A planet 1.4 times the size of Earth known as GJ 1132b, is 39 light years away. It was observed that this planet is cloaked in a thick layer of gases which can be either water or methane or a mixture of both. However, the surface temperature of this planet is 370 degree Celsius, which makes it unlikely to sustain any life.
The planet lies in the Vela constellation in the southern hemisphere, and the star that this planet orbits is much smaller and cooler than our sun. Considering the high surface temperature, the distance between the star and this planet must be really small.
Researchers believe that even though life might not seem possible on GJ 1132b, they have been able to conclude that planets around low mass stars can have atmospheres, and because of the large possibility of such stars, there can be as many opportunities of finding a habitable planet or one with extra-terrestrial life forms.
It is a known fact all planets revolve around the Sun. During the course of journey around the Sun, the position of Earth & Jupiter is that they will have face off which is known as Opposition. That is to say, an observer can easily located Jupiter by looking opposite direction to the sunset in the evening or sunrise in the morning. Jupiter will be at its closest approach and would appear more big and brighter than usual.
The opposition will be for only one day, April 9 (Mark your calendars!). The opposition occurs every 13 months, i.e. the previous one occurred on March 8, 2016 and the next one will occur on May 9, 2018. But really, why wait another year?
From today April 5, to April 14, astronomers will use a system of radio telescopes around the world to peer at the gigantic black hole at the center of the Milky Way, a behemoth called Sagittarius A* (Sgr A*) that’s 4 million times more massive than the sun. The black hole is supposedly 26,000 light years away from the Earth.
The interior of a black hole, as you know, sucks everything in. So not even light can escape a black hole, which is the reason it can never be imaged. However, the researchers at the University of Massachusetts Amherst intend to understand a lot more about black holes with the data from this project. The project is being called Event Horizon Telescope (EHT), and will be linking observatories in Hawaii, Arizona, California, Mexico, Chile, Spain and Antarctica to create the equivalent of a radio instrument the size of the entire Earth.
EHT will also be observing another super-massive black hole, 6 billion times the mass of our Sun, which is 53.5 million light years away. Hence, it is easier to observe than the Sgr A* because of such a massive size.
