One of the biggest challenges to manned space missions is the expense. The NASA rule-of-thumb is that every unit mass of payload launched requires the support of an additional 99 units of mass, with “support” encompassing everything from fuel to oxygen to food and medicine for the astronauts, etc.
A team of researchers led by Michele Fumagalli from the Extragalactic Astronomy Group and the Institute for Computational Cosmology at Durham Univ., were among the first to use ESO’s Multi Unit Spectroscopic Explorer (MUSE) instrument on the VLT.
After a 20-year search, astronomers have uncovered a grand total of 1,900 planets residing outside of the Solar System. Last year, the European Space Agency (ESA) launched the Gaia spacecraft with a mission to create a massive, three-dimensional map of the Milky Way by surveying a billion stars in our galaxy (that’s just one percent of the estimated Milky Way star population, but still impressive.)
A certain black hole is more insatiable than expected. The P13 is a black hole along the outer edge of the NGC7793 galaxy located around 12 million light years away from the Earth. It’s very luminous compared to others of its kind but as it turns out, this has nothing to do with the black hole’s size.
A Neptune-size planet beyond the solar system has telltale traces of water vapor in its atmosphere, making it the smallest exoplanet known to have the wet stuff yet, scientists say.
What if, in our quest to find another Earth, we happen upon another Venus? We should celebrate, of course. Venus is often called Earth’s “twin” because it shares of lot of our home planet’s physical characteristics: surface area, composition and density.
The presence of water ice clouds has been detected on our gas giant planets like Jupiter, Saturn, Uranus and Neptune. But, water ice clouds had not been found on planets outside the solar system.
NASA had longed to send their astronauts to outer space without aid from their Russian counterparts. To accomplish this, they need to make a perfect Space Taxi that will transport their astronauts to that space beyond.
A comet has a lot to hide. To most people, it’s among the most glamorous objects in the solar system—brilliantly illuminated, racing through space with its glowing tail streaming far behind it.
Our universe is becoming more mysterious with the attempts of understanding it deeply. The Galaxies are moving away from each other because of expanding universe which is now well accepted concept.
It might be one of your classmates, a work colleague. Or maybe even a punk kid who does oil drilling in the middle of the ocean. But NASA is sure the first humans to step foot on Mars are already walking the Earth today, meaning that smart kid you made fun of in fifth period might change history.
