00:00:00,160 --> 00:00:05,000
Gooday everybody, and welcome to Astronomy
Daily for Friday, the twenty eighth of

2
00:00:05,240 --> 00:00:10,160
July twenty twenty three. My name
is Tim Gibbs and I will be your

3
00:00:10,199 --> 00:00:21,559
host for today's episode. Will be
as usual. I have my AI assistant

4
00:00:21,600 --> 00:00:26,480
and brilliant reporter Hallie here in the
studio with me. Hallie, have you

5
00:00:26,519 --> 00:00:29,519
got some headlines for us today?
I sure do, Tim. Here are

6
00:00:29,519 --> 00:00:34,799
my top headlines for today. Massive
meteor shower to peek over Australia this weekend

7
00:00:34,799 --> 00:00:39,240
with up to twenty shooting stars an
hour. A stunning meteor shower called the

8
00:00:39,320 --> 00:00:44,320
Delta Aquariates will be visible over Australia
this weekend, providing Australia with a light

9
00:00:44,320 --> 00:00:49,320
show of up to twenty shooting stars
every hour. Delta Aquariats will provide a

10
00:00:49,359 --> 00:00:54,359
steady stream of meteors over several days
starting from the week hours, and stargazers

11
00:00:54,399 --> 00:00:59,359
won't need a telescope to enjoy the
event. Delta Aquariates is active from July

12
00:00:59,479 --> 00:01:03,600
twelfth August twenty third, with the
peak of the meteor shower taking place in

13
00:01:03,640 --> 00:01:07,519
the early hours of July twenty ninth
and July thirtieth. The peak is predicted

14
00:01:07,560 --> 00:01:14,040
for July thirtieth, twenty twenty three
at eighteen UTC, but this shower doesn't

15
00:01:14,079 --> 00:01:19,120
have a noticeable peak. It rambles
along steadily from late July through early August,

16
00:01:19,439 --> 00:01:23,959
joining forces with the August persides.
Earth Sky dot Org says. The

17
00:01:23,079 --> 00:01:26,680
name of the shower comes from the
constellation in the night sky that it appears

18
00:01:26,680 --> 00:01:34,280
to be traveling directly outward from Royal
Museum's Greenwich. RMG explains for the Delta

19
00:01:34,319 --> 00:01:38,920
Aquariads, the radiant of the shower
lies inside the constellation of Aquarius, near

20
00:01:38,959 --> 00:01:42,599
the bright star Delta Aquarii. Your
naked eye is the best instrument to use

21
00:01:42,640 --> 00:01:47,719
to see meteors. Don't use binoculars
or a telescope, as these have narrow

22
00:01:47,719 --> 00:01:52,359
fields of view. Start your meteor
watch from around two am to increase your

23
00:01:52,400 --> 00:01:57,920
chances of spotting meteors, says RMG. Once you've located Delta Aquarii on the

24
00:01:57,959 --> 00:02:00,280
sky, look away from the radiant
point. If you look in the direction

25
00:02:00,319 --> 00:02:05,680
of the radiant, you will only
see short meteors. The Delta Aquariats is

26
00:02:05,719 --> 00:02:08,439
a small to medium shower, reaching
a peak rate of around twenty meteors per

27
00:02:08,479 --> 00:02:15,360
hour. SpaceX misses attempt for record
breaking double launch attempt. SpaceX on Thursday

28
00:02:15,400 --> 00:02:20,840
again scrubbed the launch of its Falcon
Heavy rocket and Echostars Jupiter three satellite,

29
00:02:21,039 --> 00:02:25,080
missing an opportunity for a record setting
double launch. The company was scheduled to

30
00:02:25,159 --> 00:02:30,360
launch the Falcon Heavy rocket within forty
four minutes of launching a Falcon nine rocket

31
00:02:30,599 --> 00:02:34,520
carrying Starlink satellites, which, according
to a report in space Flight Now,

32
00:02:34,719 --> 00:02:39,000
would break a record for the shortest
time between Cape canaveral launches. SpaceX is

33
00:02:39,039 --> 00:02:44,759
targeting Friday, July twenty eighth for
Falcon Heavy's launch of the Hughes Jupiter three

34
00:02:44,800 --> 00:02:49,960
mission to a geosynchronous transfer orbit from
Launch Complex thirty nine A LC thirty nine

35
00:02:50,000 --> 00:02:53,199
A at Kennedy Space Center in Florida. The company said in a press release.

36
00:02:54,159 --> 00:02:58,919
The ninety nine minute launch window opens
at eleven oh four p m Eastern

37
00:02:58,960 --> 00:03:04,919
time three four Universal time, coordinated
on July twenty ninth. A backup opportunity

38
00:03:05,039 --> 00:03:08,599
is available on Saturday, July twenty
ninth with the same window. The Falcon

39
00:03:08,719 --> 00:03:14,039
nine launch is still expected to occur
around eleven ten pm Eastern time. According

40
00:03:14,039 --> 00:03:19,000
to another press release from the company, that rocket will carry twenty two Starlink

41
00:03:19,080 --> 00:03:23,159
satellites into low Earth orbit from Space
Launch Complex forty at Cape Canaveral Space four

42
00:03:23,280 --> 00:03:29,080
station in Florida. If the weather
does not cooperate with the launch, backup

43
00:03:29,080 --> 00:03:32,759
opportunities are also available just after midnight
and again Friday evening, starting at ten

44
00:03:32,759 --> 00:03:37,960
o four pm Eastern Time until twelve
to twenty six am on Saturday, meaning

45
00:03:37,960 --> 00:03:42,520
the two rockets could still launch in
a close span. The Falcon Heavy launch

46
00:03:42,560 --> 00:03:45,960
had also been scrubbed Wednesday with just
over a minute left in the countdown,

47
00:03:46,039 --> 00:03:51,520
and no reason was provided at the
time. The Jupiter three satellite is reportedly

48
00:03:51,560 --> 00:03:55,319
the largest commercial communications satellite ever constructed, and will have the wingspan of a

49
00:03:55,319 --> 00:04:02,520
commercial airliner when deployed. Astronomy Daily
podcast following on from Halley's earlier story,

50
00:04:02,960 --> 00:04:11,520
SpaceX has successfully launched twenty two Starlink
satellite. SpaceX launched a Falcon nine rocket

51
00:04:11,560 --> 00:04:17,040
with a payload of twenty two Starlink
satellites into space early Friday from Florida's famed

52
00:04:17,319 --> 00:04:21,879
Cape Canaveral, after having scrubbed the
launch of a separate mission Thursday night.

53
00:04:23,560 --> 00:04:29,120
The rocket launched at twelve o one
am Friday from Space Launch Complex forty at

54
00:04:29,160 --> 00:04:33,279
Cape Naveral Space Force Station. Up
to four backup launch opportunities were available to

55
00:04:33,360 --> 00:04:41,360
SpaceX to launch the nearly two dozen
satellites into Low Earth Object Low Earth orbit,

56
00:04:42,439 --> 00:04:46,959
where they will join Starlinks constellation of
orbitals that provide high speed, low

57
00:04:47,040 --> 00:04:56,120
latency Internet around the globe. The
launch occurred shortly after SpaceX scrubbed a Falcon

58
00:04:56,199 --> 00:05:00,279
Heavy mission that was to lift off
late Thursday. No reason for aborting the

59
00:05:00,360 --> 00:05:06,360
mission was immediately made public. The
first stage booster used in early Friday launch

60
00:05:06,439 --> 00:05:12,680
flew its fifteenth mission. After deploying
its payload in space, the launch vehicle

61
00:05:12,759 --> 00:05:17,560
returned to Earth, where it landed
upon the autonomous a shortfall of Gravitas drone

62
00:05:17,560 --> 00:05:24,120
ships stationed in the Atlantic Ocean.
Both faring halves used in the launch were

63
00:05:24,160 --> 00:05:28,839
on their second mission and were to
be retrieved by BOB, the recovery vehicle.

64
00:05:30,480 --> 00:05:36,160
Astronomers find a rare Einstein cross.
Gravitational lensing is one of astronomer's many

65
00:05:36,199 --> 00:05:42,959
great wonders, a natural lens that
magnifies the distant universe. Sometimes a lensing

66
00:05:43,040 --> 00:05:47,079
system takes the shape of a so
called Einstein cross. Those are rare and

67
00:05:47,160 --> 00:05:53,319
amazingly useful ways to study objects far
away in space and time. A team

68
00:05:53,360 --> 00:06:00,319
of astronomers recently found a new one
using the Dark Energy Spectroscope instrument mounted on

69
00:06:00,360 --> 00:06:04,480
a telescope at kit Peak National Observatory. The instrument is surveying the skies and

70
00:06:04,519 --> 00:06:11,839
has found many instances of gravitational lensing. Following observations show that the new one

71
00:06:11,920 --> 00:06:16,319
to be both beautiful and a scientific
treasutrove of information about the early universe.

72
00:06:17,199 --> 00:06:23,560
The lens system, called DSi two
five three point two five three four plus

73
00:06:23,959 --> 00:06:29,519
twenty six point eight eight four three
is actually a massive four ground elliptical galaxy

74
00:06:30,000 --> 00:06:36,480
surrounded by four blue images of a
background galaxy. Team leader Alexander Sitoka of

75
00:06:36,680 --> 00:06:45,480
Nori Lab pointed out what those images
that form of perfect Einstein cross pattern reveal.

76
00:06:46,279 --> 00:06:51,040
The four images that display consistent spectral
features tell the astronomers that the source

77
00:06:51,160 --> 00:06:55,839
is a single galaxy, which allowed
them to confirm the lens system. He

78
00:06:55,879 --> 00:07:00,879
said, the cross pattern tells them
about the mass distribution of the lens galaxy.

79
00:07:00,199 --> 00:07:10,319
Elongated mass distribution results in Einstein crosses
and spherical mass distribution, it would

80
00:07:10,360 --> 00:07:15,839
result in a Ninstein ring This latest
Einstein cross has some interesting statistics. The

81
00:07:15,920 --> 00:07:21,240
main galaxy doing the lensing lies about
five point nine eight billion light years away.

82
00:07:21,920 --> 00:07:27,519
The distant galaxy that it's lensing is
more than eleven point one seven nine

83
00:07:27,759 --> 00:07:31,319
billion light years away. Thus,
the four ground lensing galaxy is giving an

84
00:07:31,319 --> 00:07:36,800
amazing look at the galaxy in the
yearly universe. Now over to you Halley

85
00:07:36,920 --> 00:07:42,759
for a terrible joke. Absolutely,
here's another dad joke for you, and

86
00:07:42,839 --> 00:07:46,639
it's not astronomy related. I am
branching out. Why do chicken coops only

87
00:07:46,680 --> 00:07:50,959
have two doors? Because if they
had four, they'd be a chicken sedan.

88
00:07:54,560 --> 00:08:00,279
That is just a terrible joke.
