NASA’s Mars rover Curiosity has recently sent an interesting image of Mars showing a “floating spoon” type of thing on the planet. This floating spoon looks like hovering above a ridge with a shadow on the surface. Continue reading Curiosity’s finding of strange “floating spoon” on Mars
“Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying” (Arthur C. Clarke)
Life on Earth is a common thing. Life on clouds and in water looks interesting. And life on places other than the Earth (extraterrestrial life) looks…ummmm…possible. In this article, I will try to note some information ranging from hypothesis to scientific information related to the life on places other than Earth. Continue reading Life on places other than the Earth
NASA will work with two aeronautical firms, Boeing and SpaceX, in a taxi contract to take astronauts to the International Space Station (ISS) in the coming years to perform important science research and other related tasks on ISS. NASA is also thinking to use the same technologies to take astronauts to other places in space such as Mars and asteroids in the future.
This contract would reduce the U.S.’s dependence on Russia to take and bring astronauts to and from the space station. At this time, Russian Soyuz takes at least four astronauts of NASA in a year at the price of $71 million per seat. On the other hand, SpaceX noted the cost $20 million per seat in the future after the success of technological contract. Continue reading NASA’s contract with Boeing and SpaceX
UMD and NASA astronomers track an intermediate-mass black hole from syncopated flares of light.
The universe has so many black holes that it’s impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big, and colossal. Astronomers know that black holes ranging from about 10 times to 100 times the mass of our Sun are the remnants of dying stars, and that supermassive black holes, more than a million times the mass of the Sun, inhabit the centers of most galaxies.

In findings that help astrophysicists understand our corner of the galaxy, an international research team has shown that the soft X-ray glow blanketing the sky comes from both inside and outside the solar system.
The source of this “diffuse X-ray background” has been debated for the past 50 years. Does it originate from the solar wind colliding with interplanetary gases within our solar system? Or is it born further away, in the “local hot bubble” of gas that a supernova is believed to have left in our galactic neighborhood about ten million years ago?
The scientists found evidence that both mechanisms contribute, but the bulk of the X-rays come from the bubble. The solar wind, a stream of charged particles continuously emitted by the Sun, appears to be responsible for at most 40 percent of the radiation, according to new findings published in the journal Nature.
“The overarching science goal of our work is to try to answer questions like: What does the local astrophysical environment look like? And what is the environment in which the Sun was born?” said Susan Lepri, an associate professor of atmospheric, oceanic and space sciences in the University of Michigan College of Engineering.
“It’s part of trying to understand our place in the universe.” Continue reading The Source of The Sky’s X-Ray Glow
