How many Extra Solar Planets or Exoplanets have been discovered as of today?

Posted by in categories: space, sustainability

As of today, July 10, 2018. There are 3081 Exoplanets discovered and confirmed so far… Exoplanets are planets orbiting other stars or found outside our solar system.

These planets orbiting from 2842 stars. We consider these as other solar systems from which 633 of these stars have multiple planets orbiting around them just like our own solar system.

A trillion-dollar space industry will require new markets

Posted by in categories: economics, finance, space

RENTON, Wash. — Forecasts that predict the space industry to grow to a trillion dollars by the 2040s will require the development of new markets, even with the modest annual growth rates needed to achieve that goal.

A panel session June 26 at the Space Frontier Foundation’s NewSpace 2018 conference here noted that several reports in the last year by investment banks predicted that the global space economy, currently valued at about $350 billion, could grow to $1 trillion or more in the 2040s.

One report by Goldman Sachs predicted the industry would reach $1 trillion in the 2040s, noted Jeff Matthews, a consultant with Deloitte who moderated the panel discussion. A separate study by Morgan Stanley projected a “most likely outcome” of a $1.1 trillion space economy in the 2040s. A third study by Bank of America Merrill Lynch was the most optimistic, seeing the market growing to $2.7 trillion by the same timeframe.

Jupiter’s Moons Leave Signature Spots in Its Aurorae

Posted by in category: space

Despite being wildly different from Earth in almost every way, Jupiter does feature some familiar phenomena—including aurorae, what we call the Northern and Southern lights. But Jupiter’s aurorae have something Earth’s don’t: strange features caused by the Jovian moons.

Scientists analyzing data from the Juno spacecraft spotted some of these anomalies in action. They saw swirls and spots caused by Jupiter’s moons Io and Ganymede. And, as is often the case, things weren’t what they seemed from far away.

Milky Way still bears the 10-billion-year-old scars of a galactic collision

Posted by in category: space

Galaxies collide with each other on a pretty regular basis. Our own Milky Way, for instance, has gobbled up dozens of smaller galaxies in the past, and Andromeda is currently hurtling towards us at 109 km (68 mi) per second. An international team of astronomers has now found evidence of a celestial smash-up between the Milky Way and an unknown dwarf galaxy that took place around eight to 10 billion years ago, and forever changed the face of our home galaxy.

According to the researchers, the evidence for this cosmic collision is all around us, from the bulge at the center of the Milky Way to the spread-out halo at the very fringes. The now-defunct dwarf galaxy has been dubbed the “Gaia Sausage,” after the ESA’s Gaia satellite used to plot out the trajectories of its stars, and the apparent shape those measurements revealed.

“We plotted the velocities of the stars, and the sausage shape just jumped out at us,” says Wyn Evans, co-author of the study. “As the smaller galaxy broke up, its stars were thrown out on very radial orbits. These Sausage stars are what’s left of the last major merger of the Milky Way.”

Did Something Massive Smash Into Uranus?

Posted by in categories: energy, space

Uranus really is strange. Not only does it rotate on an axis that sits at a 98-degree angle to its orbital plane, but, unlike the other giant planets, it doesn’t appear to release more heat than it receives from the Sun. Its magnetic field, too, appears warped compared to the Earth’s. An impact could perhaps help explain some of these strange traits.

Scientists have been simulating giant impacts into Uranus since the early 1990s, according to the new paper published in the Astrophysical Journal. This time around, researchers built a new simulation with the newest and best available data of the planet’s composition. This allowed them to model how a giant impactor, perhaps one to three times the mass of Earth, would have deposited “material and energy inside Uranus” and how much debris would be left over, from which moons could form.

“This study provides some great new insights into what might have happened all those billions of years ago, with material left over from the impact possibly even serving to trap some of that heat inside,” Leigh Fletcher, Royal Society Research Fellow at the University of Leicester, told Gizmodo.
