Ngāi Tai ki Tāmaki buys land under Macleans College for $97m 15 Mar, 2021 04:00 PM 5 minutes to read Macleans College is a decile 9 school with uninterrupted sea views at Bucklands Beach. Photo / Brett Phibbs An Auckland iwi, Ngāi Tai ki Tāmaki, has agreed to buy the land under Macleans College in a $97-million deal that dwarfs any previous treaty-based school transfer. The small iwi, which only 498 people said they belonged to in the 2013 Census, has decided to exercise a right to buy the land that was agreed under a Treaty of Waitangi settlement in 2015. But the value of the prime site with uninterrupted sea views at Bucklands Beach has escalated more than seven-fold since the iwi and the Crown reached an agreement in principle on the settlement - from $16m to more than $120m. ....
BRIAN KOBERLEIN, UNIVERSE TODAY A white dwarf isn t your typical kind of star. While main sequence stars such as our Sun fuse nuclear material in their cores to keep themselves from collapsing under their own weight, white dwarfs use an effect known as quantum degeneracy. The quantum nature of electrons means that no two electrons can have the same quantum state.
When you try to squeeze electrons into the same state, they exert a degeneracy pressure that keeps the white dwarf from collapsing. But there is a limit to how much mass a white dwarf can have. Subrahmanyan Chandrasekhar made a detailed calculation of this limit in 1930 and found that if a white dwarf has more mass than about 1.4 Suns, gravity will crush the star into a neutron star or black hole. ....
The Most Common Stars in Our Galaxy May Be More Habitable Than We Thought EVAN GOUGH, UNIVERSE TODAY 17 JANUARY 2021 Red dwarf stars are the most common kind of star in our neighbourhood, and probably in the Milky Way. Because of that, many of the Earth-like and potentially life-supporting exoplanets we ve detected are in orbit around red dwarfs. The problem is that red dwarfs can exhibit intense flaring behaviour, much more energetic than our relatively placid Sun.
So what does that mean for the potential of those exoplanets to actually support life? Most life on Earth, and likely on other worlds, relies on stellar energy to survive. The Sun has been the engine for life on Earth since the first cells reproduced. But sometimes, like all stars, the Sun acts up and emits flares. ....
Astronomers Have Identified Another Important Aspect of Planets That Could Host Life 13 JANUARY 2021 We are, by now, pretty familiar with the concept of the Goldilocks zone. Also known as the habitable zone, it s the distance from a star at which liquid water can be present on the surface on a planet - not so hot as to be vaporised, nor so cold as to be frozen.
These conditions matter because we count liquid water as a vital ingredient for life. But it s not the only criterion that can help us to assess a planet s potential habitability; according to new research based on decades of data, there are also Goldilocks stars. ....
