When looking out of a train window, things close by seem to move past faster than things that are far away.

Ada, 7, wants to know why things close to the train windows zoom by really fast, while things further away seem to go by much slower.
A huge solar flare flashes in the middle of the sun on Sept. 6, 2017. A separate image of the Earth provides scale.
At a time in the sun's cycle when space weather experts expect less solar activity, our star is going bonkers with solar flares and coronal mass ejections. What effects will Earth feel?
Looking inside a quantum computer.
As companies make quantum computers available through their cloud services, take a look at what it means for computing to move beyond classical mechanics and into quantum physics.

If we could mimic spider silk, it could revolutionise the fibres we use on a daily basis.
When is it too hot to fly?
Major airports around the world will see more frequent flight restrictions in the coming decades because of increasingly common hot temperatures.
Methods stemming from decades of research on disordered materials are used to describe algorithmic phase transitions, and to design new algorithms in machine-learning problems.
The last thing the spider saw before everything went black.
If a huge huntsman spider is sucked into a vacuum cleaner, can it crawl out later? Lucy, age eight, really, really needs to know.
Does God exist?
There remain many mysteries that are beyond science. Does that mean that a God truly exists? A scholar gives reasons for this possibility.
Defecation duration is surprisingly similar throughout the mammal world.

New parenthood got our fluid dynamics experts thinking about what ends up in the diaper. They headed to the zoo and the lab to come up with a cohesive physics story for how defecation works.
Mathematicians make a splash with new theory that could lead to breakthroughs in 3D printing, climate science and forensics.
It will be quick and it will be hot.

It's been five decades of microwave popcorn and piping hot leftovers in home kitchens. A serendipitous discovery helped engineers harness radar to create this now ubiquitous timesaving appliance.
Look ma, no gravity!
Every moment of life on our planet has had the force of gravity in the background. But the prospect of long-distance space travel means it's time to figure out what happens to our biology in its absence.
Will NSW physics students learn what these lines represent?
NSW's proposed new rigorous physics syllabus refocuses on the fundamentals, but it'll require investment in teaching skills so all students can benefit from it.
Scientists theorised, disproved, revamped and finally created a bizarre new form of matter in just five years.
Why can’t we see the spaces?
The reason you feel things as solid is all to do with electrons.
Scientific and technological innovations and economic policies promoting growth at all costs have created a consumption and production vortex on a collision course with the Earth system.
Tiny CubeSats are ready to be our eyes in the skies.

As technology advances, tiny satellites no bigger than a loaf of bread have advanced from just proving they work to being big contributors in answering science questions.
Static electricity can cause more than just a bad hair day.
These mini lightning bolts have been known for millennia. Understanding static electricity at the atomic level opens the door for new technologies – as well as ways to cut down on the tiny zaps.
Liquid water develops different properties above around 50℃.
