In October 2017, astronomers announced the first detection of gravitational waves from the merger of two neutron stars earlier that year. The event also rung in the era of multi-messenger astronomy, as more than 70 telescopes observed the event’s afterglow in optical light, X-rays, gamma rays, and more. Now, an X-ray signal dubbed XT2 from a galaxy 6.6 billion light-years away has revealed another neutron star merger, which left behind a single, heavier neutron star with an incredibly powerful magnetic field: a magnetar.

Today’s stories…
First results from ExoMars Trace Gas Orbiter During its first year in orbit the ExoMars Trace Gas Orbiter has made some surprizing discoveries about the impact of the recent global Martian dust storm and an apparent lack of methane in the red planet’s atmosphere.
Dragon spacecraft destroyed in dramatic explosion The first crew Dragon two capsule which successfully flew to the International Space Station in March has been destroyed in a major explosion at the Cape Canaveral air force station in Florida.
Stratolaunch test flight Stratolaunch has successfully undertaken the first test flight of the company’s behemoth twin fuselage six engine jetliner designed to launch satellites into space.
May Skywatch We tour the night skies of May which play host to the annual Eta-Aquarids meteor shower generated by Halley’s Comet.
Last Wednesday’s show…
New model for Nova explosions Scientists will need to go back to the drawing board to come up with new ways in which powerful explosions – known as novae – can occur on the surfaces of white dwarf stars.
Explaining super-luminous novae Astronomers have discovered that shockwaves generated during nova explosions can dramatically amplify their power and brightness.
NASA’s InSight Detects First Likely ‘Quake’ on Mars NASA’s Mars InSight lander has measured and recorded for the first time ever a likely “marsquake.”
New physics needed to explain differences in the Hubble Constant New observations are showing that differences in how fast the universe is expanding now compared to how fast it was expanding billions of years ago are no statistical accident.
The Science Report Climate change is now threatening the world’s doomsday vault. The world’s second largest colony of emperor penguins almost wiped out. Extreme ocean winds and wave heights are increasing around the globe. A small bone behind the knee, which was once rare in humans is becoming more common. Palaeontologists have unearthed a new species of hadrosaur dinosaur in Mongolia. History revisionists spewing lies and cherry-picked half-truths for racist and political propaganda
SpaceTime Background SpaceTime is Australia’s most respected astronomy and space science news program. The show reports on the latest stories and discoveries making news in astronomy, astrophysics, cosmology, planetary science, galactic and stellar evolution, physics, spaceflight, and general science. SpaceTime features interviews with leading Australian scientists about their latest research. The show is broadcast coast to coast across the United States by the National Science Foundation on Science360 Radio and around the world on Tune in Radio. SpaceTime is available in Australia as a twice weekly podcast which averages around three million downloads annually. It’s hosted on line through Bitez.com on all major podcast platforms. SpaceTime began life in 1995 as ‘StarStuff’ on ABC NewsRadio. Stuart Gary created the show while he was NewsRadio’s Science Editor, evening presenter, and news anchor (a position he held for more than 17 years). Gary wrote, produced and hosted StarStuff, consistently achieving 9 percent of the Australian radio audience share - according to Neilsen ratings survey figures for the five major Australian metro markets (Sydney, Melbourne, Brisbane, Adelaide, & Perth). The StarStuff podcast was hosted by ABC Science on line achieving over 1.3 million downloads annually. Sadly, the popular program was axed in 2015 during ABC budget cuts. Rather than remain with the ABC, Gary resigned to continue producing the show independently and rebranding it as SpaceTime. The first episode of SpaceTime was broadcast on February 8th 2016 and the show has been in continuous production ever since. SpaceTime now reaches an audience almost three times greater that it achieved as StarStuff and continues to grow.

ayeee it was worth it the teacher said my website was the best one and i got two A’s on it!! :))
finished a 4 hour html homework now i gotta study math and programming im gonna kms i swear

As promised. Which ones should I do next?
Hi, do you know any resources to start learning coding, preferably for free? Ty!!
Hiya! ✨ Yeah, I’ll see what I can find! However! Online courses often have a build in a code editor. Don’t. Honestly, do not. Get a full software and install it, don’t be restricted to just an online code editor, even on a basic level. First of all decide what language you want to start learning. For complete beginners, I’d recommend Python or C.
💡 codeacademy (this I’ve tried myself and yep, it’s really well written and good for beginners; it doesn’t have many courses tho) 💡 programmr.com 💡 codeavengers💡 code.org💡 Bucky’s wonderful tutorials (these are amazing! I’ve only done the c++ ones, but they were really well explained and included stuff like installing a software as well!)
And now here are some “tools” to use while programming:
🔌 stackoverflow - biggest platform there is; you can ask them anything, but it’s probably been asked before so try looking on it at first🔌 cppreference.com - has all the information about c++ built in libraries, functions, variables and anything you’ll possibly need 🔌 python visualizer - helps you visualize code if you don’t have a compiler on your laptop - they also have other languages🔌 learnpython 🔌 python tutorial🔌 game development with pygame - do something FUN! It’s not that hard, just try it That’s about it! Hope this helps! x
