My name is Evan.
24 years young.
Listener and observer.
This blog is full of what gives me passion, pleasure and joy.
Amazing day with family and friends. Bike ride home was the icing on the cake.
Feeling happy and content. Lets keep these good vibes coming.

I would very much like a Chesterfield sofa.
“I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up—many people feel small, because they’re small and the Universe is big, but I feel big, because my atoms came from those stars” - Neil deGrasse Tyson
A deep optical image of the afterglow of the gamma-ray burst GRB 090429B, arguably the most distant object known in the universe.The light from this object has been traveling towards us for about 13.2 billion years, or 96% of the age of the universe. Since the universe is not static but expanding, today this object is much farther away than 13.2 billion light-years - more like about thirty billion light-years. It tells us that 13 billion years ago, this event was more than 17 billion lightyears closer than today. The expansion of the universe is like blowing up a balloon with stars painted onto its surface; an expansion of spacetime itself.
The most distant objects in the universe are also the oldest — or at least that is how they appear to us, because their light has had to travel for billions of years to get here. They are also extraordinarily faint since they are so far away, and only in the last decade have astronomers been able to stretch their vision using the newest telescopes and clever techniques.
A NASA spacecraft circling Saturn has discovered a wispy oxygen atmosphere on the ringed planet’s icy moon Dione, but you wouldn’t want to live there. For one thing, you wouldn’t be able to breathe — Dione’s atmosphere is 5 trillion times less dense than the air at Earth’s surface, scientists say.
Dione’s atmosphere was detected by NASA’s Cassini spacecraft, which spotted an ultra-thin layer of oxygen ions so sparse that it is equivalent to conditions 300 miles (480 kilometers) above Earth. On Dione, there is one oxygen ion for every 2,550 cubic feet (90,000 cubic meters), but it’s still enough to qualify as an atmosphere, Cassini mission scientists announced Friday (March 2).
“We now know that Dione, in addition to Saturn’s rings and the moon Rhea, is a source of oxygen molecules,” Cassini team member Robert Tokar of the Los Alamos National Laboratory in New Mexico, who led the new study, said in a statement. “This shows that molecular oxygen is actually common in the Saturn system and reinforces that it can come from a process that doesn’t involve life.”
Dione is one of Saturn’s smaller moons and is about 698 miles (1,123 km) wide. It orbits Saturn once every 2.7 days at a distance of about 234,000 miles (377,400 km) — roughly the same as that between Earth and its moon, according to a NASA description.
