Starship Asterisk*

Here is "Martian Sunset" on Earth. This picture I took on 22nd of May 2014 with OLYMPUS FE-280 from LJUBLJANA, when southwestern wind brought Saharian dust to Europe.

Question for Nereid. Why are Gravitational Micro Lensings so unpopular? I'll quote from B. Scott Gaudi 2007: http://arxiv.org/abs/0711.1614v1 “I don’t understand. You’re looking for planets you can’t see around stars you can’t see.” – Debra Fischer, c. 2000 “Microlensing is a cult.” – Dave Koerner, ...

What about fiber optics? Not at such dimensions, but let say few km.

Hello Harry!
LMC has astronomical latitude b= aprox. -85 deg, so it is near south ecliptical pole, which is always 90 deg from the Sun. So when LMC is at zenith, Sun is near horizon, the sky is bright and it is impossible to see LMC!

With my question about LMC I went off the topic.
So here is project, which is about dynamic of our Galaxy- RAVE:

Hallo Harry!
I know that, but the question still remains.

You would see LMC in zenith at geographical latitude aprox. 70 deg south!

I'm serious!
Why you can't see with naked eye LMC straight over your head- at zenith?
It is nice classical astronomical question.

Here is a nice question:
"Why is impossible to see Large Magellan Cloud in zenith?"

What is wrong with gravitational lensing? I think its wonderful!

But perhaps you are referring to something else? The time-dilation observed in the high-z 1a SNe light-curves? Here is lovely article about it! G. Goldhaber et al. arXiv:astro-ph/0104382 v1 24 Apr 2001 If you mean the observations of the times of Jovian satellite phenomena (occultations etc), then ...

In other cases the frequency will stil increase! It s energy paradoxon. Eternal radiation at event horizon with increasing frequency?! Probably I am wrong. But why not! 8) Just do not forget, that there are other kind of radiations (we have four forces) in universe than electromagnetic radiation! T...

You forgot to mention SN Ia lightcurve decline redsift!
BTW first observation of doppler efect was made by Ole Roemer (1644-1710).

I have only one observer in mind- the outside observer. If the oscillator is increasing frequency (like pair of neutron stars or BHs), the outside observer will see in some cases constant frequency of gravitational radiation. In other cases the frequency will stil increase! The question is can gravi...

I have a question or two! What would hapen to gravitational oscillator, which is falling into BH? Are there solutions for gravitational waves under event horizon? Singularity; it knows for the rest of the universe & universe knows of it thru gravitation. Why not to comunicate with singularty wit...

Perhaps there is correlation between brithtness profile radial function (magnitude per arcsec^2)- measure for central BH mass and absolute magnitude of GC?

I took GC as cube. It is just estimate.

1.4 ly

I made estimate that HD209458b lost about 4% of its mass till now. I did not publish it, I made similar aproch as:
Roche lobe effects on the atmospheric loss

How can I get good photometry of Gamma Pavonis?
