Astronomers have watched the young binary star system SVS 13 for decades. Astronomers don’t know much about how planets form around proto-binary stars like SVS 13, and the earliest stages are especially mysterious. A new study based on three decades of research reveals three potentially planet-forming disks around the binary star.

If Axions are Dark Matter, we've got new Hints About Where to Look for Them
If dark matter is out there, and it certainly seems to be, then what could it possibly be? That is perhaps the biggest mystery of dark matter. The only known particles that match the requirement of having mass and not interacting strongly with light are neutrinos. But neutrinos have low mass and zip through the cosmos at nearly the speed of light. They are a form of “hot” dark matter, so they don’t match the observed data that require dark matter to be “cold.” With neutrinos ruled out, cosmologists look toward various hypothetical particles we haven’t discovered, and perhaps the most popular of these are known as axions.

40 Telescopes Watched the Sun as the Parker Solar Probe Made its Most Recent Flyby
Sometimes in space, even when you’re millions of kilometers from anything, you’re still being watched. Or at least that’s the case for the Parker Solar Probe, which completed the 11th perihelion of its 24 perihelion journey on February 25th. While the probe was speeding past the Sun, it was being watched by over 40 space and ground-based telescopes.
According to a US Auditor, Each Launch of the Space Launch System Will Cost an “Unsustainable” $4.1 Billion
This will likely come as a surprise to no one who has closely watched the development of NASA’s next giant rocket, the Space Launch System (SLS), but it’s going to be expensive to use. Like, really expensive – to the tune of $4.1 billion per launch, according to the NASA Inspector General. That’s over double the original expected launch cost.

Are there any moons that are made of gas?
The planets in our solar system come in two forms: Some are rocky, and some are gaseous. But all of the moons in our solar system are rocky, even the ones that orbit gas giants. So why aren't some moons in the solar system made of gas? And are there gaseous moons anywhere in the universe?
Can you really purchase and name a star?
Some companies make money out of 'selling stars', or rather selling opportunities to name them, perhaps as a gift to a loved one. But is it really worth the money?
