That’s some tough parenting.
Stars commonly engulf planets, but some can survive and even outlive the star.

Astronomers found compelling evidence that the water in our solar system came from interstellar space. This water around a distant protostar is quite similar to the water found in our solar system, and on Earth.
Astronomers report the discovery of two new exoplanets orbiting a bright sun-like star about 175 light years away. The newfound alien worlds, designated HIP 104,045 b and HIP 104,045 c, were classified as a Jupiter analog and a super Neptune planet, respectively. The finding was detailed in a paper published March 2 on the pre-print server arXiv.
The radial velocity (RV) method to detect an exoplanet is based on the detection of variations in the velocity of the central star, due to the changing direction of the gravitational pull from an unseen exoplanet as it orbits the star. Thanks to this technique, more than 600 exoplanets have been detected so far.
Now, a team of astronomers led by Thiago Ferreira of the University of São Paulo in Brazil, reports the detection of two new exoplanets using the RV method. They observed a solar-type star HIP 104,045 with the High Accuracy Radial Velocity Planet Searcher (HARPS) spectrograph on the 3.6m telescope of the European Southern Observatory (ESO) in La Silla, Chile. The observations, conducted as part of the Solar Twin Planet Search (STPS) program, resulted in the discovery of two massive extrasolar worlds.

On July 21, 1969, Neil Armstrong took that first fateful step onto the Moon. The exact moment occurred just as our planet’s standard universal time hit 2.56 am. But what time was it for Neil?
There’s currently no answer to that question, but with plans in place to inhabit the Moon, that may need to change.
At a recent meeting in the Netherlands, members from space organizations around the world agreed that we need to implement a proper lunar time zone – an internationally accepted common lunar reference time that all future missions can use to communicate and navigate with ease.
This could rethink our view of the world as once-habitable.
Venus has long been discussed as a former ‘ocean world’ like Mars, but a new study in PNAS shows this era may have been short lived.
If there is a social media phenomenon getting some kind of popularity, Meta will try and jump in. We have seen the company copy different kinds of formats ranging from Stories to short videos after seeing the success of other platforms. Now, the Mark Zuckerberg-led company is working on a decentralized text-based app.
Meta confirmed this development in a statement but didn’t give out details about when it plans to release the app.
“We’re exploring a standalone decentralized social network for sharing text updates. We believe there’s an opportunity for a separate space where creators and public figures can share timely updates about their interests,” a Meta spokesperson said.
High-performance, realistic computer simulations are crucially important for science and engineering, even allowing scientists to predict how individual molecules will behave.

Scientists have always used models. Since the ancient Ptolemaic model of the universe through to renaissance astrolabes, models have mapped out the consequences of predictions. They allow scientists to explore indirectly worlds which they could never access.
Join Sir Richard Catlow as he explores how high-performance computer simulations have transformed the way scientists comprehend our world. From testing hypotheses at planetary scale to developing a personalised approach for the fight against Covid.
