'Second Earth' exoplanet found right under our noses – just four light years away


Re: Green? Blue? Brown?

And I raise with the original paper*:

"Although Proxima is considered a moderately active star, its rotation period is about 83 days (ref. 3) and its quiescent activity levels and X-ray luminosity are comparable to those of the Sun."

*That is from the abstract, so it is accessible from outside the paywall. And there's a reference which should be also accessible

Prof Hawking to mail postage-stamp space craft to Alpha Centauri using frickin' lasers


star wars

It's actually the opposite: we can do that exactly because of laser weapons (http://spie.org/newsroom/technical-articles/4853-did-adaptive-optics-end-the-cold-war).

It looks like the star wars project might do some good in the end.

To be fair, most of the research is actually coming from astronomical observatories, given that the military technology is still secret.

Balloon-lofted space podule hits 30,000m


Re: Helium balloons

wait, what? You just need simple fusion of hydrogen to get helium. You need Supernovas to get above iron.

Still, I'm not sure how "simple" fusion is. We can do it in the labs, it's just not giving us more energy that we put in, but if the point is to produce helium, not energy it might work. Again, I don't know how convenient this is, but it is done already in the labs.

It's like controlled fusion: always one release into the future (sadly).

It should be available as option, but it's supposed to be default in 16.10 in one year. Although I don't blame them for not sticking a completely new and untested software in a Long Term Support release like 16.04 will be.

Re: Free you say?

Can anyone show me where it says that after the first year you will start to pay? In the microsoft website I can't find it and this seems something that they should be forced to put on a small footnote.

As much as I would love this to be true (see icon), I think this is just BS.

And I won't be downgrading, I'm already on version 14.04. That's more than 4 versions ahead.

Progress source replenishes international space station


Re: Question for El Reg's space cadets

SpaceX and the other companies that will carry american astronauts are required to provide emergency escape systems.

My understanding is that if this accident would have appended with astronauts on top, they will be able to escape. Actually, it is believed that the dragon capsule survived the explosion, but there was not enough time to tell the capsule to deploy the parachutes.

Of course, there is always going to be something that they were not prepared for, but this IS rocket science.

Google opens 'Inbox' heir-to-email trial to biz users

Thumb Up

Have an upvote for actually sharing your experience/point of view.

I've also been trying inbox for a month now and I have your same feelings. It works ok and have very nice feature.

I really like the snooze button and the fact that overall it helps to keep the inbox clean from old email: if it's something that you are going to do in the future just snooze, if you have completed it click on "done". Of course this could be done in the old gmail/outlook, but here it's the whole point of the interface.

On the other hand, this means giving more data to google (can we possibly give more?) and the interface needs a bit of polishing, it needs time to get used to some changes with respect to gmail and, as usual, some features have disappears. Also I really don't like the fact that you have to use chrome, although with a little help from an user-agent switcher plugin you can use it on firefox (which gets me even more disappointed as there's no reason to restrict it only to google's browser).

Overall, I think there's good ideas and possibly the good stuff will flow back into gmail in the future.

Lenovo shipped lappies with man-in-the-middle ad/mal/bloatware

The problem with some new Lenovo laptops is that they don't come with the licence key, so you are stuck with what you have. Still, you can always download a proper OS for free (as in free speech and free beer).

Dark matter-hunting boffins spot EXCITING signal in X-ray spectrum


The idea is that dark matter annihilates producing standard particles that then decays into photons. We expect to be an X-ray signal from dark matter (in some models), the problem is that we don't know the frequency (free parameter) or the intensity (depend on some models).

I guess you have never played KSP...

To put something into the sun you have first to get rid of all earth orbital velocity. There are some tricks that will help you, so you can get down to half of that, but it's still a lot of energy to burn.

Distro diaspora: Four flavours of Ubuntu unpacked


Re: I don't get it

The problem is that there are a lot of unity-specific patches that will not give you a clean gnome 3 installation for istance; so if you don't want just to try a new window manager but you have already decided to use it, the different flavour are the way to go.

However, being linux you are also free to apt-get install whatever you want


In 14.04 unity will have the ability to move the menu on the window bar, which make a lot more sense to me.

However I will stick to Ubuntu Gnome, I find it more beautiful than unity

'Weird' OBJECT, PROPELLED by its OWN JETS, spotted beyond Mars orbit by Hubble


Re: First example?

Actually you explain with the assimetry of the asteroid, as it was hinted in the article...

"This YORP effect (named after the four scientists who contributed to the theory: Yarkovsky, O'Keefe, Radzievskii, and Paddack) has been suggested as a reason for the relative paucity of small, asymmetrical objects within our Solar System in comparison to rounder rocks, and the search is now on for more observations of the theory in action."

'Long Time Ago' and 'Far, Far Away' records broken by new GALAXY


Re: jasonalanward

The concept of horizon in cosmology is a bit misleading. It is true that nothing can travel at a speed larger than the speed of light, however very distant galaxies are observed having a recession velocity larger than c. This is congruent with general relativity because its the space itself that is expanding. In fact, due to the accelerated expansion, in a distant future we will be able to see only objects in the local supercluster.

Final countdown for NASA's NuSTAR X-ray black hole telescope


Yes, Italy has a space agency...

From Wikipedia https://en.wikipedia.org/wiki/San_Marco_programme

"The project resulted in the launch of the first Italian-built satellite, San Marco 1, on December 15, 1964. With this launch Italy became one of the first countries in the world to operate its own satellite, after the Soviet Union and the United States"

Billionaire astro mining venture long on hype and timescale


Re: Is it really true?

It depends on the asteroids. On the earth, the heavy elements sunk in the core, while in the crust there are only light elements (and stuff bring up by volcanoes). Some asteroids were formed from the protoplanetary nebula, so they will have the mean composition of all earth. But others were formed from collisions of small planets and therefore there are asteroids with the same composition of the mantel and the core (basically iron, nickel and other heavy elements)

Antimatter asymmetry: new results bring solution closer


Re: Re: Re: Re: Can someone cleverer than me please explain?

And at those early times, the universe was very dense and ionized, so the electric attraction was far greater then the possible gravitational repulsion. It is very difficult to justify this segregation


Re: Re: Re: Re: Can someone cleverer than me please explain?

We don't know if antimatter is gravity repulsive (they are trying to measure this with anti-hidrogen experiments), but again, those experiments on decay ratios are showing that there's a measurable difference between matter and antimatter. The idea is that before the annihilation of the primordial matter and antimatter, around 10^-9 of the total antimatter decayed leaving a surplus of matter.

Of course this is science and this can be all wrong. It would be cooler if antimatter is repulsive because it could be stored more easily and solve lots of transportation problems ...


Re: Can someone cleverer than me please explain?

We should be able to se gamma rays from the annihilation in the border between the hemispheres. But we don't see them.

And also you have to find an explanation for this asymmetric distribution.

Those experiments, on the other hand, prove that there's a measurable difference between matter and anti-matter in the sense that the latter decays more easily. And that's the explanation of why just one out 10^9 survived annihilation. (we can use this decay ratio to find out if an alien is made of antimatter before shaking his hand)

Galaxy is teeming with homeless planets


Re: Does this answer some of that unexplained mass

Those planets (MACHOs) can explain just some of the dark matter.

From the analysis of the Cosmic Microwave Background radiation, we know that barionic (normal) matter is just 5% of the matter-energy of the universe, while gravitational matter is around 30%. So most of the matter of the universe has to be some kind of exotic (non baryonic) matter.

Neutrinos still FASTER THAN LIGHT in second test


Actually one possible explanation is that neutrinos interact with the matter (I know that the cross section is very very small, but we still don't have lot of data about neutrinos' physics) and it's like sound through rock or light through plasma


No, we don't. Neutrinos from 1987's supernova arrived just at the precise time on which they were expected if they were travelling at c. They arrived 3 hours before the light just because they were emitted 3 hours before the light, being the light emitted only when the shock wave reaches the exterior of the star

Russia’s space telescope in orbit
