For the first time ever, scientists are set to reveal a photograph of a supermassive black hole that is millions, perhaps even billions, of times more massive than the sun.
What does the Milky Way really look like? The truth is that we only have the vaguest idea.
NASA's 'Mars Helicopter' has successfully completed a series of tests and is ready to take flight over the Red Planet. NASA conducted two test flights where the drone reached an altitude of just two inches. But the team says that it is all they need. This could possibly prove that the helicopter works in Mars-like conditions. In January 2019, all the pieces, making up the flight model (actual vehicle going to the planet) of NASA’s Mars Helicopter, were put to the test.
Stars could be described as being volatile and aggressive, particularly early on in their life cycles. However, scientists have only just found one that could be referred to as ‘salty’ – in a literal and figurative sense.
Sirius, a system of two stars - Sirius A and Sirius B - is the brightest object that we can see from the Earth. However, an asteroid called (4388) Jürgenstock briefly passed in front of Sirius on Monday (Feb 18, 2019) night. Sirius was almost entirely to fade for a few tenths of a second, as the 3.1-mile-wide asteroid flew by. The occultation, as it is called, was visible in parts of Mexico, six US states, and Canada.
Tuesday (Feb 19, 2019) will bring with it, the “super snow moon.” This moon will be at its closest to Earth at 4:07 am EST (0907 GMT). A 'supermoon' occurs when a full moon coincides with the moon's perigee, or the point in its elliptical orbit at which it is closest to the Earth. This makes the moon appear up to 14 percent larger and 30 percent brighter than usual. We, earthlings, see this event when the moon is full or nearly full and also at its closest point to our planet, along with its slightly elliptical orbit. This close approach is called perigee by astronomers.
The ‘super blood wolf’ lunar eclipse was a globally popular event for several reasons. One, it occurred during the moon’s perigee or closest point in its orbit to Earth. This made it particularly bright and clear on the night in question (January 21, 2019). This also meant that the red color typically associated with full lunar eclipses was in strong effect for many people (and their recordings).
Astronomers and lunar scientists had calculated that there would be a spectacular blood moon on January 18, 2019. These events are given the name because the moon turns a strong red color before falling into a complete eclipse. However, this was a more than average lunar occlusion. The satellite was also at the closest point to the Earth, as it began this eclipse, thus upgrading its status to a ‘super’ blood moon.
Temperatures inside the one-liter canister dived to -52 degrees Celsius, which resulted in the death of cotton sprouts during an experiment by Chang’e 4 probe attempting the creation of a self-sustaining mini biosphere on Moon.
Asteroid AG3 missed the Earth by more than three million miles (4.9 million km), 12.86 times the distance from Earth to the moon, which may be considered a narrow miss on the cosmic scale, especially given the speed of space rocks. A giant asteroid dubbed Asteroid 2019 AG3, a massive space rock, flew past Earth on Monday (Jan 14, 2019), in the early hours of the morning (GMT), according to NASA.
What will happen to our galaxy in the future? Astronomers actually have a relatively detailed picture of what may happen to the Milky Way, through scientific and mathematical models of this galaxy. This data indicates, for example, that our galaxy will collide with its near neighbor, the Andromeda, at some point. However, this is not thought to be likely to occur for about eight billion years, by which time humanity may or may not even exist.
At one point in history, every form of popular media about spaceships portrayed them as shiny, silver saucers or rockets that gleamed as they took off or landed! More time and practical experience with space flight have distanced humanity from this type of imagery. We came to learn that high-tech carbon-fiber and other similar compounds were more likely to survive blasting into space.
A few days ago, NASA presented footage of its craft, New Horizons, as it completed a fly-by of a specific object in the Kuiper Belt. This mission was a success as the vessel was able to capture images and data on its target a certain amount of accuracy.
According to reports coming from the Chinese aeronautical authority, CNS, human exploration has pushed another frontier for the first time. This undiscovered country is the ‘far side’ of the moon, which is normally never seen by anyone but is thought of as containing pristine insights into life in the early days of the solar system that are not found on Earth.
One day in the far-flung future, a child may turn to their caregiver and ask, ‘Where did the ringed planet go?’ Admittedly, this is with the presumption that the solar system, as it is now, as well as the human race, are still around! These questions could arise because scientists have found that Saturn’s hallmark rings will be gone in 300 million years.
The solar system in which we live is bordered by a ‘ring’ of cosmic detritus known as the Kuiper Belt. Therefore, the objects found within this belt are the coldest in the system, since they are located at the farthest possible distance away from the sun.
The last few missions to bring new crew members to the International Space Station (ISS) have been unusually eventful, even for launches into space. Firstly, the personnel experienced a jarring vessel failure. This event quickly became the subject of intrigue and speculation, even though the crew members were able to resolve it themselves. Those astronauts and cosmonauts made it safely to the ISS.
There’s a new dwarf planet in our solar system, and it’s the most distant one scientists have ever discovered. This tiny world, formally known as 2018 VG18, but nicknamed Farout, is about 18 billion kilometers away, roughly 3.5 times the distance to Pluto from Earth. The pink cosmic body was nicknamed after its discoverer’s exclamation!
The flight was the first launch of a spacecraft, from the United States soil with humans on board, to reach the edge of space (50 miles high). The test flight was also the first time Richard Branson's space tourism startup has gone more than 50 miles above the Earth. This launch earned both the pilots commercial astronaut wings from the US government and put Virgin Galactic on track to become the first private company in the world to take paying customers to space. The launch has huge implications for a growing industry aiming to fly civilians on a regular basis.
