Exciting times in astronomy and astrophysics:

Electromagnetic and gravitational waves observed together for the first time, from a nova* called GW170817 caused by the collision of two neutron stars. More. Among other really cool results, a demonstration that as Einstein predicted gravitational waves travel at the speed of light.

Half of the mass of the universe, previously missing, has been found hiding between the seat cushions. More. This is the ordinary ("baryonic") matter we know about and are -- we were pretty sure it had to be somewhere, based on models of the universe, but couldn't see it because it's not hot (i.e., inside stars) and so isn't bright -- as opposed to the still-unobserved "dark matter" that we think is causing other, weirder effects. (via)

New hypothesis about knots in the early universe suggests that they provide an answer to both why the universe is three dimensional (knots can only form in 3D spaces -- they can be unraveled in higher dimensional spaces) and what powered the early inflationary universe. (via)

A pome for a moon-day:


On a Beach at Night, Walt Whitman

On the beach at night,
Stands a child with her father,
Watching the east, the autumn sky.

Up through the darkness,
While ravening clouds, the burial clouds, in black masses spreading,
Lower sullen and fast athwart and down the sky,
Amid a transparent clear belt of ether yet left in the east,
Ascends large and calm the lord-star Jupiter,
And nigh at hand, only a very little above,
Swim the delicate sisters the Pleiades.

From the beach the child holding the hand of her father,
Those burial-clouds that lower victorious soon to devour all,
Watching, silently weeps.

Weep not, child,
Weep not, my darling,
With these kisses let me remove your tears,
The ravening clouds shall not long be victorious,
They shall not long possess the sky, they devour the stars only in apparition,
Jupiter shall emerge, be patient, watch again another night, the Pleiades shall emerge,
They are immortal, all those stars both silvery and golden shall shine out again,
The great stars and the little ones shall shine out again, they endure,
The vast immortal suns and the long-enduring pensive moons shall again shine.

Then dearest child mournest thou only for Jupiter?
Considerest thou alone the burial of the stars?

Something there is,
(With my lips soothing thee, adding I whisper,
I give thee the first suggestion, the problem and indirection,)
Something there is more immortal even than the stars,
(Many the burials, many the days and nights, passing away,)
Something that shall endure longer even than lustrous Jupiter
Longer than sun or any revolving satellite,
Or the radiant sisters the Pleiades.


Offered in honor of yet another family viewing of an ISS transit being blocked by overcast. Wet winter means fewer chances to wave hello to the astronauts (current number: 6). Contrast this, if you dare, with Spring and Fall.

The ISS has a livestream of several HD cameras pointed at earth, as they test several models to see which off-the-shelf hardware survives space the best. If you get a grey screen, wait a few seconds as that means its' switching views; if it's black, the they're probably over the ocean at night (check the location finder on the right). It's fun to put this fullscreen on my second monitor. (via)
