Some hot giant planets get larger as they are heated by their stars | New Scientist
Giant planets known as hot Jupiters appear to be growing in size as they are heated by their stars over billions of years.
Why these 4 planets are getting as much X-ray radiation as 10,000 suns
The V 1298 Tau star system contains four young planets, orbiting close to their parent star, where they are baked in X-ray radiation.
Orbiting the young star V 1298 Tau, more than 350 light-years from Earth, at least four planets wind their way around their orbits in the developing solar system. These worlds huddle close to their stellar companion, which bathes the worlds in X-ray radiation.
This pressure from the star likely strips the innermost pair of these worlds of any atmosphere which might develop, leaving them as bare balls of rock. The outer two worlds, however, may have climates that are far more complex.
What's in the morning sky? Several planets putting on a show before sunrise

ORLANDO, Fla. – If you've looked up before the sun has broken the horizon, you've likely seen the show space has been putting on for us. Jupiter and Saturn have been hanging out close together before midnight and the Mars joins the party in the wee hours of the morning. All three planets are visible in the southern/southeast sky until the sun comes up.

Just before sunrise Venus peeks above the horizon and becomes the 4th visible planet the morning sky. Venus will become more visible in the morning with grouping of planets later in June and especially July as the sunrise becomes later.

Planets must be formed early, study finds
The answer, says Łukasz Tychoniec, a graduate student at Leiden Observatory and lead author of the new paper, is that "we need to look earlier instead of looking for missing mass." With his collaborators, Tychoniec used images from ALMA in the Atacama desert in Chile and the VLA in New Mexico to study protostars in the Perseus molecular cloud, a giant star-forming region about 1000 light-years away.
These infant stellar systems are thought to be between 100,000 and 500,000 years old. If we assume our own sun is 45 'human years' of age (instead of its roughly 4.5 billion years), then those protostars are equivalent to less than two days old. But apparently these toddlers are already busy making planets.
Baauer Releases Sophomore Album 'Planet's Mad'
"I wanted to make an album sort of like ones I really loved when I was a teen, which were instrumental, kind of conceptual electronic albums by people like Fatboy Slim, Daft Punk, Chemical Brothers and The Avalanches," Rodrigues says. "Those were albums I really loved listening to, so I wanted to give it a shot and build my own world the way I thought those artists did."
The producer adds that he started conceptualizing Planet's Mad by creating hundreds of 30-second long loops. While he felt that many of those snippets of music were perfect at that length, he knew he needed to make them longer. "I always sort of resisted albums because it felt like that's not how people really listen to music," he says. "I listen to music in little bite-sized chunks, and I feel like most people do.
How elements mix deep inside giant planets? - Tech Explorist
It could offer insights into the evolution of planetary systems and guide scientists hoping to harness nuclear fusion as a new source of energy.
An international team that includes scientists from the Department of Energy’s SLAC National Accelerator Laboratory has devised a new way to quantify how chemical elements behave and mix deep inside icy giants. This new experimental setup is expected to reveal detailed insights into the formation and evolution of planetary systems.
