"These collisions are exceedingly rare and so this is a big deal that we actually get to see evidence of one," said Andras Gaspar, an assistant astronomer at the University of Arizona's Steward Observatory and lead author of a research paper announcing the discovery. "We believe that we were at the right place at the right time to have witnessed such an unlikely event with NASA's Hubble Space Telescope."
"The Fomalhaut star system is the ultimate test lab for all of our ideas about how exoplanets and star systems evolve," added George Rieke, a Regents Professor of Astronomy at Steward Observatory. "We do have evidence of such collisions in other systems, but none of this magnitude has been observed in our solar system. This is a blueprint of how planets destroy each other."

Two (potentially) exciting new exoplanet discoveries | Space | EarthSky
Scientists just announced 2 new exciting updates about exoplanets. One is a potentially habitable world similar in size and temperature to Earth. The other is a possible new planet – possibly with rings – orbiting the closest star to our sun, Proxima Centauri.

Astrophotography in your backyard #2: shooting Venus and other planets | Digital Camera World
The lockdown is helping to create the best night skies for years. The lack of pollution from aircraft and cars, and a cut in light pollution from the vehicle headlights, has contributed to sparkling night skies in recent weeks. Either way, there hasn't been a better week for decades to get out into your back garden (or poke a camera out a window) to capture some sparkling celestial events.
In the second of our five-part series on backyard astrophotography we are going to look at the planets.
Mysterious 'Planet Nine' on the solar system's edge may not be real | New Scientist
Things aren't looking so good for Planet Nine. Astronomers have been seeking signs of a purported giant planet in the outer reaches of our solar system since 2014, but new observations hint that it may not actually be there.
In 2014, astronomers noticed that rocks in the outer solar system called extreme trans-Neptunian objects, or eTNOs, seemed to be inexplicably clumped together . That clumping, along with their strange elongated orbits, could possibly be explained by the gravitational influence of a planet with five to ten times the mass …

Earth Day 2020! Celebrate our home planet with these online activities | Space
Most of us won't be venturing into the great outdoors on Wednesday (April 22), but you can still celebrate the 50th anniversary of Earth Day in style.
The space agency has combined a variety of educational resources into a 50th anniversary toolkit , which is designed to get conservation messages across to young people — and the rest of us as well. NASA has also launched an #EarthDayAtHome campaign to help the public celebrate.
* * *
"Fifty years ago, people around the world celebrated the first Earth Day (April 22, 1970). Organizers selected dates and planned activities specifically to engage young people in the growing environmental awareness movement," NASA officials wrote in a statement on the toolkit's home page .
The Top Five Planets Destiny 2's Pyramids Could Blow Up Soon
And yet those all seem like tiny facets when you compare them to a new fall expansion that almost certainly will add a giant land mass or two to the game like we saw with Forsaken and Shadowkeep before it. So how exactly does that work?
* * *
"Story-wise" the Pyramids should arrive to our inhabited zones by the start of next season, and it may actually be time for Bungie to consider wiping an entire planet from the game in order to make room for new stuff.
Earth Day In A Time Of Pandemic: Our Planet As The Missing Stakeholder
When Business Roundtable published its now-famous statement of August 19, 2019, on the purpose of the corporation, it was hailed by many as an inflection point in modern business. Here were 184 leading CEOs advocating for corporations to take a broader societal role and responsibility.
Now, this terrible pandemic is reminding us that our economy, our society, and our species is part of something bigger, more holistic, and more powerful. In some ways, the convergence of the 50 th anniversary of Earth Day with this daunting pandemic crisis puts a spotlight on the ongoing challenges we face in our relationship with the physical world, both natural and human-made.
Raising Captain Planets – Press Releases on CSRwire.com
Apr. 20 /CSRwire/ - Some of you may recall the 1990s American TV cartoon program, “ Captain Planet and the Planeteers ” where five “planeteers” across the globe use the power vested in their rings to foil villainy and summon Earth’s ultimate superhero — Captain Planet himself.
What I really like about the program is that it instills environmental awareness among the young. Children learn that pollution, deforestation, poaching, and other environmentally destructive and unethical activities are just “bad behaviors.” They understand that they should stand up to such activities and be Earth’s superheroes.
