SpaceX’s launch of the all-private Inspiration4 crew mission, scheduled as soon as Wednesday night, is an all-commercial affair that leaves NASA largely on the sidelines. And that’s just fine with NASA Administrator Bill Nelson.
Thanks to the most advanced telescopes, astronomers today can see what objects looked like 13 billion years ago, roughly 800 million years after the Big Bang. Unfortunately, they are still unable to pierce the veil of the cosmic Dark Ages, a period that lasted from 370,000 to 1 billion years after the Big Bang, where the Universe was shrowded with light-obscuring neutral hydrogen. Because of this, our telescopes cannot see when the first stars and galaxies formed – ca., 100 to 500 million years after the Big Bang.
NASA astronaut Mark Vande Hei will stay in space until March, giving him a record-setting spaceflight.
The solar system's outermost planet, Neptune, reaches opposition today, and here's how you can catch a glimpse of the distant gas giant.
During Juno’s extended mission, every orbit is like a new adventure. Each orbit is a little different, and NASA says the natural evolution of Juno’s orbit around the Jupiter provides a wealth of new science opportunities. But for most of us, what we look forward to on every perijove – the point in each orbit where the Juno spacecraft comes closest to the gas giant – are the incredible images taken by the camera on board, JunoCam. As Juno’s “eyes,” the camera provides a unique vantage point no other spacecraft has been able to give us.

In the classical theory of general relativity, black holes are relatively simple objects. They can be described by just three properties: mass, charge, and rotation. But we know that general relativity is an incomplete theory. Quantum mechanics is most apparent in the behavior of tiny objects, but it also plays a role in large objects such as black holes. To describe black holes at a quantum level, we need a theory of quantum gravity. We don’t have a complete theory yet, but what know so far is that quantum mechanics makes black holes more complex, giving them properties such as temperature and perhaps even pressure.
