The fate of the Sun is sealed. It was sealed by gravity in the earliest days of its formation. In several billion years the Sun will swell to a red giant, cast off much of its thin outer layers, then collapse to become a white dwarf.
White dwarfs are interesting objects. They form when their gravitational weight is balanced by the quantum pressure of electrons . They don’t experience any nuclear fusion or gravitational heating, so once formed they just gradually cool down.

The discovery: New data shows that TOI-1075 b is one of the most massive super-Earths discovered so far.
Key facts: The planet, nearly 10 times Earth’s mass, orbits a small, red-orange star about 200 light-years away. Its year, once around the star, takes only 14 ½ hours.
View planets, winter constellations at Observatory open house: Indiana University Kokomo
Learn more about neutrinos — tiny, nearly massless particles that travel at near light speeds — and how they are studied at the Indiana University Kokomo Observatory’s free monthly open house Sunday, November 13.
Patrick Motl, professor of physics, will begin the evening at 7 p.m. with a presentation about neutrino astronomy, which allows for observation of astronomical objects with neutrino detectors in special observatories.
New Study Finds Debris Of 10-billion-year-old Planets in Milky Way Galaxy
A group of astronomers, led by the University of Warwick, has claimed that they have discovered the oldest star in the Milky Way galaxy. Ruins from planetesimals in orbit are being absorbed by the oldest rocky and icy planetary systems which astronomers have now discovered.
The group of astronomers created a simulation of two unique white dwarfs that were observed by the European Space Agency's GAIA space observatory for this study.
How many types of precipitation can a planet have? - Big Think
Here on Earth, the water cycle – including its solid, liquid, and gaseous phases – is the top factor in determining what the climate and weather of any particular location is going to be like.
But we only have a “water cycle” here on Earth because our temperatures and pressures allow water to exist in all three phases.
Solar panel discovery paves way for exploration of distant planets
A team from the University of Cambridge proposed an ultra-thin photovoltaic cell design that can tolerate irradiation in space that causes damage and lowers efficiency of conventional solar cell materials.
This means it would be possible to deploy them in higher orbits around the Earth, such as the Molniya orbit that passes through the centre of our planet's proton radiation belt.
Could Jupiter's Heat Waves Help Solve a Planetary Energy Crisis? - Eos
Jupiter has been unusually prominent in both headlines and the night sky in recent months—not only because the gas giant made its closest approach to Earth in 59 years but also because it's been surprisingly hot.
Jupiter's churning atmosphere is famous for its many cloud bands, storms, and the Great Red Spot. Close-up observations only began with the Pioneer probes of the 1970s, and the planet can still surprise.
The Hottest Planet In The Solar System | IFLScience
Defining how hot or cold a planet is can get complicated. Just take Earth as an example. The temperatures in the tropics are definitely different from the temperatures at the poles. Variations in temperature, even extreme ones, are common both in the atmospheres and at locations across the ...
